Haven’t seen much about how to do this, so posting a bit of info. I use my parking brake regularly. One day I pulled it and the steel block at the parking brake lever end of the cable separated from the cable. I ordered a new one off of Rock Auto and finally got around to swapping it out. RAYBESTOS BC97335 Element3. The part itself was only $13.
Firstly, let me say I did not really know the best way to do this when I started. What I am writing is what I found to be the best way. Firstly, you must remove the lower cushion of the rear seat in order to access the rear of the front cable where it connects to the two rear individual wheel cables.
There are two bolts that need to be removed in order to remove the lower rear bench seat cushion. After they are out it is just a lift and pull forward to disengage two hooks that hold the seat base to the chassis.
After the rear seat is out, you will obviously also need to remove the center console. This is something I have done so many times with this Jeep, I forget the amount of times, and each time I hope it will be the last. You need to remove the chrome shifter bezel ring, black plastic that goes around shift control module, and then remove the rubber cup holder . Under the rubber cup holder should be a 10 mm bolt that holds the middle, and rear of the plastic console to the body. At the rear of the console when you pry the plastic cover off form the bottom, and remove the foam, you will see two small torx head screw that hold the rear of the console down.
The front driver’s seat was removed as well. I am not sure if this is necessary or Mopar maintenance spec, but the carpet has a stiff protective under layer. This makes it very difficult to bend or roll the carpet up. Since I have had the front seat out before, I just disconnected the single electrical connector under the seat, pulled the four bolts and put the seat on the ground beside the Jeep. The lower portion of the seatbelt strap remains attached to the seat, so if you want to put the seat further away you would need to deal with that. When that is done, this is what you should see.
Cable housing End
The blue grommet circled in red is one of the cable housing ends. Since one end of my cable came off, I just pulled the cable out of the housing from the back end. You can also see in the photo above I needed to remove the floor moulding, rubber moulding partly, and the B pillar plastic moulding to let the sear belt go outside with the seat.
The red line shows the path the cable takes under the carpet. Both ends click into a hole with pushable plastic locks. Since the cable sheath is very stiff it was difficult remove the cable ends from the metal housing, so I just crushed or ripped off with vise-grips. At the bottom middle you can see the two individual rear wheel brake cables attaching to a bracket where the front cable slots in.
There is a 10 mm nut holding the cable sheath down to a mounting stud on the floor. The red arrow shows the normal path of the cable. The blue end circled in red shows the part that normally clicks into the metal housing.
Swapping cable housing
After removing the old cable housing, route the new one in under the carpet. This is a good time to vacuum. I found 6 dollars, a bunch of french fries, a long lost phone mount magnet, and a few other treasures. I clicked the back end into place, and then routed the front to more or less where it was going to need to go to attach to brake lever. Maybe it would have been better to attach it at the front first, and then rotate the spring loaded ratchet, and lock it with a grenade pin, or maybe the way I did it was correct. One thing I will say is be careful because the spring mechanism has a fair amount of force
All in all it is a fairly simple job, the hardest part being knowing what to take out, and taking all the trim pieces out carefully without breaking flimsy plastic tabs, and the difficult, but important part of connecting the front of the brake cable to the lever attachment point. Put it all back together in reverse, and that is about it.
N.B. Some of the seat bolts go through the floor, so you can see daylight when they are removed. I coated all of these with anti seize. Putting the center console back in place requires you to pay attention to about 5 different points of contact at the same time. Including the center console forced air pipe, front console mounting alignment pins, console front alignment tabs, seatbelts, brake lever, gear shift, etc.
18 mm Seat back Bolts seem to bolt into a threaded nutsert that is likely in an enclosed channel. I took the opportunity to pull these out, wire wheel the excess rust off of them, and put them back in with a liberal dose of anti-seize. They were very difficult to remove, and if they were any thinner bot material, or less hard a grade they likely would have snapped off. I don’t know if I will ever have reason to remove them seat backs, but at least I know I will probably be able to.
Every year, usually in Spring and fall, but since I run A/TW more about when i have wheels off than anything, the calliper slide pins are taken out, cleaned up on a wire whee and greased with silicone lubricant. I usually pack some extra into the rubber dust shields to make sure they are positively pressurized with grease, and then put it back together. Usually the lower bolt on the front callipers has some rust at the bell end. The last year or so I noticed the calliper slide pins were getting putted, and the rubber at the end furthest into the calliper bracket was getting deformed. I looked to buy some replacement pins and rubbers in Canada, but the cost was close to $100 even at a trusted parts store. They only came with the pad spring clips and those were not needed. I bought the parts, and then took them back realizing that eventually I would probably swap out the callipers, and the price was not much more expensive and included all hardware. Enter Rock Auto and I was able to buy new pins and rubbers for all four corners for about $25 delivered to my door. Will be putting these on and servicing the brakes soon.
Will post a few more photos of the swap and install to show condition of older pins and rubbers.
Chrysler dealers may use the wrong fluid when servicing the vehicle, or selling you fluid. It is important you double check this. I have had a dealer tell me they had to order it by the case when I said I needed two quarts. They did not want to order it to stock. I went somewhere else. Dodge Vipers used the same system for a couple years, and maybe some of the Ram trucks. It is not a widely used or understood system. If you have a hydraulic fan insist on getting the correct Mopar MS-10838 fluid, and if your fluid is red, flush and change for correct if you have hydraulic fan.
Some of the Jeep WK / WH models have hydraulic cooling fans similar to Ford Lincoln and a few other makes and models.
On the Jeep the hydraulically driven fan is powered by the power steering pump and shares the same fluid as the power steering system. Mopar spec: MS-10838 fluid is added through the power steering fluid reservoir, and drains when your badly designed Jeep return fluid lines pop off and drain your fluid on the ground.
This is a very complex system controlled by the computer, and a number of different sensors including air con, transmission temp, engine temp et al. More about this can be seen in these threads.
Note if you are having issues and unsure if your solenoid is bad, you can remove the thermostat wire (See image labelled below) mid center right of the motor, just under the fuel rial, and the fan should ramp up to a fairly high speed almost immediately.
This is a project I have been working on for awhile, and it is 85% complete. The aux battery project itself was done in combination with the rear storage project since they would need to function together as well as independently.
The rear sliding drawer storage system was built to be removable, and would incorporate some aspects of the rear aux. electrical system, but I needed the battery and electrical system to be totally independent of the drawers when needed, as well as be safe. Electrical system fires are apparently one of the main sources of problems for Overland Expedition vehicles. A statistic that likely does not improve with time, vibration, wear and tear.
I have seen people mount their batteries on WKs in a few different places. Under the hood, but that has included moving the stock electrical fuse and relay boxes. Anything that runs the risk of lowering reliability and increasing the chance of hard to troubleshoot electrical issues is not an option. My family owned a Land Rover growing up, and I owned a 1971 MGB GT, so I am very familiar with reading electrical diagrams and tracing electrical faults, even manually simulating the alternating signal on a DC fuel pump in the back seat of said MGB to keep it going while my gf drove it home.
I have seen people mount them under the left hand side rear tire next to the subframe, but in the event of a rear quarter crash, or off-roading and dropping that tie off a rock this was not an option. A Jeep forum member showed me where his was, and this made sense to me.
I bought a fairly solid aluminum minimalistic battery holder meant for Optima “6 cylinder” batteries. I bought it off Amazon, and here is the link:
When the link is dead I will kill it, and the photos will remain.
I still have to add some venting, but this should not be too much of a problem with these batteries and the Ctek charging system. As I understand it, hydrogen gassing tends to happen more often if a battery is being overcharged.
Step 1. Mounting Battery
After struggling with how to mount it, I opted (no pun intended) for what was available at my local hardware store.
I bought a four foot length of lightweight drilled angle steel, cut a 1 inch line on the angle, and folded the ends over, overlapping holes, drilling out as necessary and ended up with “perfectly” fitting mounting struts. I used stainless steel bolts drilled through the fender well with the nut on the inside, and silicone seal to keep moisture and dirt on the bottom side of the wheel well.
Below: By request are some additional detail photos showing how the Optima tray is mounted.
I purchased a length of slotted angle steel from my local hardware store. Made a cut along the angle, and folded the tabs over.
Here I used double nits and lock washers to make sure nothing would vibrate loose. As you can see I only used three out of the four mounting positions for the tray.
Above: Here you can see the process used to align and level the battery tray. In all honesty this seems to me to be the best tray to give battery a solid footing and take minimal space.
I used a fair amount of washers as necessary to level the battery tray, and nylon lock nuts as well as lock washers as needed.
Above: Attempt at making nice straight uniform lines to make an even cutout for battery poke through.
Below: Semi final product. Eventually I will add some border or moulding, flashing etc to it to give it a less chainsawed look. For now the fender liner functions to hold the electrical panel in place, still holds the cargo cover, and also serves as a mount for the Travall Pet Guard cargo separator.
Eventually I took a half assed attempt at putting the plastic fender liner back in. It all started pretty civilized, but in the end I was hacking i tup with a sawzall in my driveway at dusk.
Now that I had a battery mounted the question became how to get power to it. Currently I am not using a ground wire, but just grounding the battery to the steel unibody. Paint having been wire wheeled off, and bolted solid. Still I know this is not as good as copper, but for the charge coming through from the alternator, it should be fine. (for now). I will do some more advanced testing once the project is finalized.
As mentioned above, I started with a basic idea for charging a second battery, but decided to get something more or less foolproof, and reliable that did not require any manual intervention, and actually charge battery more effectively and faster than the alternator and a direct line of heavy gauge wire would.
It is called a “Dual” because it can also take a solar panel current direct and act as an MPPT charger. If you know anything about Solar and MPPT chargers, this Ctek box actually comes in at a pretty good price point just to be used as an MPPT, or at the very least a proper solar charge controller because most for sale on the market undercharge the battery. If you are unfamiliar with Ctek, check out a coupe episodes on Jay Leno’s garage were he explains the benefit, and how much better they are for batteries in the long or short run.
Using the United States Coast Guard USCG wiring chart for reference on all my wiring
The most important tools and parts for an electrical project like this are proper terminal crimpers, proper correctly sized terminals, heat shrink, (heat gun) and research.
After looking at the issues with hydraulic crimpers, and matching dies to crimpers, I opted for old school mechanical power. I must say this is one of the manliest tools I own, and I still have machetes and snake sticks left from my time living in the rain forest in Costa Rica dealing with Terciopelo aka Fer-de-Lance.(venomous snakes) Anyway, this makes crimping AWG 6 child’s play and $60 -$80 it is a bargain. Try to buy pre made battery and alternator cables and you will see this thing pays for itself very quickly.
Given that I am also wiring up the solar powered system in my trailer it will get more use. Big wire is not used out of necessity for voltage or amperage, but to lessen voltage drop which is prevalent in DC applications. (See USCG chart above)
Keep in mind when buying heat shrink tube you need it big enough to cover the terminal housings, not just the wire. (Not that I made that error) Let’s just say I have a lot of extra terminal ends, and heat shrink laying about.
Before anybody feels the need to comment on the sloppy cutting of the inner plastic fender, and the sacrilege of cutting into sacred irreplaceable Jeep “Tupperware” I was unsure I would even put these plastic inner wheel-well liners back into place. In the ned it was a little difficult to find the lines and cut, but if anybody is considering this, please contact me and I am sure I can come up with more accurate templates o measurements to help. Finally I put it back because it made it all simpler to mount the wiring board, still use the cargo cover when desired, and protect the stock wiring hidden by the plastic.
The Ctek ended up getting mounted on a piece of plywood down and out of the way. Probably important to remember, some of those steel terminals are direct to the battery, so proper insulation, or coverage is needed. Mine are normally covered by the rear storage drawer.
Step 2. Running wire from Alternator/battery
I removed the passenger and rear seats, (super easy) as well as the center console, which I have removed a dozen times battling the Shift Control Module problem. (Final solution, replaced it)
I used a backup set of 8 gauge booster cables. I don’t know if they are UV resistant, but they should not see any sun to speak of.
Above: Here is wire going through firewall. I put it through large grommet on right of steering. I used plastic cable protector here, and for much of the 15 foot run, but also used red rubber coolant hose under the floor carpet and rear seat.
Above: There is a nice natural channel above the heating duct to run the wire to right of LHD WK driver’s legs. You can see the imprint on the carpet from the line of the plastic center console.
Above: here you can see I taped a small low voltage wire to the side of the main charging wire. Although I did not really plan this out in advance, from experience, I know running wires while you have the chance is a good idea. The light gauge orange wire may be used for a switch from the front panel, to a relay i the rear for pretty much anything. No idea at the moment.
Above: Here I followed the natural curvature of the floor, and used the stock wire protection as much as possible. Here I used rubber heater hose I had laying around (Elephant hose mod) as protector. I feel the corrugated black plastic would be easier crushed and compromise the wire and insulation inside.
Above: Coming up the right hand side, I used Zip ties to hold it in place. Another reason I put the stick inner wheel-well grey “tupperware” back in place.
Rear seat back in place.
Above: Rear seat back in place. Being careful not to pinch wire with rear seat bracket.
Above: Cut the carpet slightly to allow a cleaner exit for cable and insulation.
Above: Zip tied the front section, and put console back on.
Above: With main wire now in place, time to put inner fender with “laser cut precision battery hole” back into place. IN all honesty may two main concerns for the batter were that it was “level” stem to stern with the jeep, and that it cleared the slide in rear drawers easily. In order to mount a fuse and relay panel I was considering building a frame, over the battery and all sorts of things, and then decided, “well if the rear storage space is going to be full most of the time, I will not be able to see anything anyway, so who cares about light through the windows.”
Left: At some point I began wiring up the fuse block. It is a Bluesea Marine panel, and has both a positive and Negative post. That means all pos and neg wires run to this panel.
Here you can see an AWG 4 gauge wire with ring terminal and heat shrink waiting to be crimped and terminated.
Originally I had the fuse panel on the outside for easy access, but after a bit more use, decided I needed the real estate for the Dc-AC Inverter. Originally I had holes going through from relays n the back to fuses in the front.
Above: Photo is from testing, prototyping phase. Red LED I added, because I wanted to incorporate a few things that “added a cool factor” and while at the electronics store grabbed things that I felt might come in handy. In all seriousness, this is switched to the off position for the on board Air compressor relay. Using a 40 amp relay with a Viair 450 (or something like that I will check) allows me to leave it on all the time when a hose is attached. The light is just an extra to let me know it is off or on and is visible from the driver’s seat, which is how I positioned it in the board.
Above: Relay board now looks like this. I considered moving the inverter to the other side, but for the high amperage cables needed, I figured it was best here. There is enough room for some air flow top and bottom, and the cable organization works perfectly this way. This is a Stanley 750 watt non-sine wave inverter. I did not do any great amount of research on this, just grabbed it on 50% off end of season sale at local hardware store for $75. I have used a rice cooker plugged in to cook rice I have plugged my RV TV in to it and it draws almost nothing, and I have plugged in my Ctek battery maintainer charger to keep the RV trailer battery topped up overnight, so essentially going Solar/alternator to DC battery via Ctek DC-DC to Dc-AC inverter to AC-DC charger to let me run DC lights etc in RV. Maybe to the least inefficient, but all part of experimenting with new system at the moment.
Fitting the window shaped plywood electrical board into the window opening took a few tries. When I ordered two sheets of 1/2″ Marine Grade plywood for the drawer system, it came protected by two sheets of chipboard, which gave me a lot of material for mocking up stuff. It fits into the natural contour of the plastic interior window liner, behind the Travall Pet guard. Holding it in place I drilled a hole and with large flat washers mounted a 1.5″ 5/16th bolt coming out of the plastic wall. There is a hole in the plywood that slips over it, and I use a flat washer and wing nut to tighten and remove. Its not perfect, because it can be dropped easily, but works for now.
For the switch panel I found a “Marine switch panel” on Amazon. I am a little suspect, but it feels pretty good, and 6 switches, and panel plus USB, lighter socket, and dodgey Volt meter for less than $50, is hard to pass up. Considering it all comes wired up, and a pretty nice job at that, and it is a winner, at least for now.
I say dodgy Volt meter because it does not give you real accurate battery level. For that you need a shunt and proper meter.
I have a template fo the wooden board shape, and will be making one for the other side, as well as replacing this one eventually, maybe.
Above: One word of warning I will give, and you will pick up on this pretty quickly. This is what the relay board looks like to the civilian passerby in the right/wrong light. I plan to spray tack a mesh fibre to the window to block any view inside. I have gone through US-Canada border a couple times so far, but do not want to return to my Jeep to see it surrounded by a SWAT team and demolition team trying to diffuse my refrigerator battery during these heightened times of security.
40 Amp Relays also purchased off of Amazon. Five of them for $12 with mounting brackets. They click lock together which can be a good thing to save space and make assembly more rigid, but will be a real pain to take apart, or replace with one that is not exact same design
For the switch panel something else I need to adjust for security purposes is the lighting. Currently I have set it up in the safest way for electrical shorts and load protection (I think), but I have no easy way of turning off LED switch lights or voltage meter while still keeping power flowing. The switch panel has three hot leads running into it all separately fused. One for LED backlights, one for Voltage Meter, USB charger plug and lighter socket, and one for something else.
I will probably set up a big mechanical kill switch, but for now main power flows direct from battery to the 100 amp fuse panel. The run is so short, I am not sure it is worth the extra hassle to put in a breaker or fuse. With only 1.5-2 feet of AWG 4 cable, I am unsure what could happen that fused protection would help. Anyway, more to the point, all those pretty LED lights sure do attract passerby’s attention at night.
If we are to look at software or devices that companies simply stop “supporting” we can begin to see how planned obsolescence a concept first enacted in ca. 1923, https://en.wikipedia.org/wiki/Planned_obsolescence to get past market saturation and have customers shorten their replacement cycle based on fashion, style, et al.
How far have electronics companies gone past that with planned software bloat, software changes that make previous hardware unusable for all but the most basic functions? How do we stop this? Will it ever stop? How can we let tech companies claim to be sustainable if they force the unnecessary “recycling” of millions of devices too often?
Here is another article on this, and many more are out there.
Day 1: This blog has been set up as a place to highlight and comment on the elevated degree and increasing speed in which planned obsolescence, or #engineeredobsolescence is being built into machines in order to increase sales, decrease product life and somehow consumers are going along with it.
Well this is a chance for us to highlight these things, for experts to comment and explain why and how it happens, and how much is necessary.
Product development not only plans for an exit strategy product end life plan, but companies also bring products to market that are not the best thing available, but what they think the next iteration they can get people to pay for. Because of that paying customers are coerced into buying a product that has already been replaced by the company, just that the replacement is not available for sale yet.
Ever have your smartphone slowdown around the time a new model is released? Do you have a tablet or computer that you paid full rice for a few years ago, that now can not even access basic internet? Do you drive a vehicle whose parts wear out making it prohibitively expensive to fix at an age and milage that 20 years ago would have been considered round 1 of a vehicle’s life? Disposable cars? Have prices decreased commensurate with their decreased life span? No, quite the opposite, they have gone up.
What about all the miracle technology that has trickled down from Formula 1, and product development and technological innovation over the years? Has this resulted in increased fuel economy? Yes to some degree, but largely due to a reduction in vehicle weights due to cheaper and lighter materials, safer designs and less polluting vehicles. Mostly the tech has gone into making vehicles more powerful, faster and able to propel your average soccer mom’s SUV / Mini van through a Starbucks front window faster than you can say “If I have to tell you to stop sticking your tongue out at your sister I will turn this car around.”
Well in all seriousness that would take quite some time to say, but still you get the idea. In 1983 a 5.0 liter Mustang was 173 hp. Now your average run of the mill Chrysler mini van is 285 hp. Because we are all in a hurry, and need the power to overtake another car so we can get, well,
