Today I installed a K Suspension headlight wire harness; if you are not familiar with this it is a parallel harness that uses the old headlight plug to trigger a new relay so it pulls power right from the battery for brighter lights. I also replaced all bulbs with LED and swapped to an...

Does anyone have any recommendations for a low profile/simple trailer brake controller to put in our XJs? It's a 2001 and did not come with a tow package and is currently wired with a 4 pin. So I know I will have to upgrade to a 7 pin. I would like something low profile since so many bolt to...

I know shims sound like modification, but this is about a factory setup. I recently replaced the springs on an XJ I bought last month with Dorman heavy duty leafs and Moog replacement coils. At the same time I replaced the lifted shackle with a factory replacement and all new shocks. It sits...

How heavy does your steering feel? I owned a 98' for a decade but it has been gone for about 5 years now. Since then I have had Subaru's, my wife's Honda and an F150 that was over assisted. The steering on this new to me 01' XJ feels very heavy, enough that I can not easily steer with one hand...

I am having some confusion on what size the front leaf to frame bolt is. I am finding part numbers referencing M14-2.0x120mm but various parts suppliers are listing 9/16" or 5/8" bolts. I know these are all similar size bolts but length and thread pitch are very important. I want to make sure I...

I came across a factory radio for the 01 XJ I recently bought. It came with a crappy old aftermarket unit and the speakers are really quiet so I picked it up. Pulled the radio, unplugged the adapter harness, factory connectors plugged right in to the factory radio and immediately a relay starts...

Does anyone know where I can find a wiring schematic for a second electric fan? I have additional connectors so I can add another 40A fuse in the factory fuse box. I want it to only work when the ignition is on and it will be on a separate temp sensor form the A/C condenser fan. What signal...

After being without a Jeep for the last 5 or 6 years I bought a 2001 XJ Sport that has a good interior and body. Up here in WI everything is so rusted out. The bad is that the rear springs are completely shot; inverted by an inch or more just sitting int he driveway. It has a 2" front spring...

My 98' XJ likes to drive me nuts... a couple of the current problems. Do you guys think these would be the sign of a bad computer or a short in the harness(s) Engine off, key out of the ignition... The cruise control module by the battery will start making a loud noise like an electric motor...

I have a 98' XJ that has had electrical gremlins in the interior wiring for years. I also have a lack of power and mpg compared to when I first bought it. I have had it into several reputable mechanics and even had the computer reflashed a couple of months ago with no luck. Because I have so...

98' XJ 4.0 AW4 with 155k on it. An on going issue for the last couple of years. Running rich to the nose yet occasionally throws a running lean code on bank 1. Now it runs rich to the point of spitting droplets of gas out the tail pipe and stalling at stops after it has warmed up. Goes down...

My 98' 4.0 drives down the road fine once it clears it's throat but when at idle the exhaust smell is really strong and it stumbles dropping cylinders and sprays a mist of unburnt fuel out the exhaust pipe. Of course mileage has dropped to 9.5mpg. The O2 sensors are 2.5 years old but only have...

Alright I have finally narrowed my death wobble down to the WJ LCAs that I am running, specifically the design of the rear bushing. Has to do with the angles/geometry combined with my current OME lift. At any rate I am now in the market for a full set of high quality control arms. I will be...

Alright I have a 98' that I recently installed a DPG 2.5" Ultimate OME kit on and now I have horrible death wobble. For reference I had the front end rebuilt 2 years ago, all new bushings, tie rod ends and bearings. The steering stabilizer is a 1 year old Rancho that looks in good shape (not...

Just curious to see what tires everyone is running on their rigs and what they think of them (good/bad). I am always seeing Q & A about sizes but rarely read what Brand/Model tire they are running. I have been running Goodyear Silent Armors 30x9.5 for the past 3 yrs. about 41k on them and...

I have decided to sell my 98' Cherokee. I had 4.10 gears swapped into my axles (30 front 8.25 rear) and a Detroit Trutrac put in rear. I have access to a wrecked XJ with a D35 rear that I could pull for free. Do you guys think it is worth swapping the axles and selling mine with the 4.10s for...

I am thinking of getting a second set of wheels/tires for commuting. I would like to go as light as possible to try and help with mpg. Thinking less weight is easier to spin up and keep moving. Together with lower friction street tires vs. ATs should be noticeable at the pump. I am...

I am trying to find a 2 core aluminum radiator. 1 core isn't cutting it, and 3 brass/copper couldn't keep up in 115 degree heat rush hour crawl. I recently read that my 98 with factory tow and heavy duty cooling package came with a 2 core. Not sure if this is true, but it seems like that's what...

It's engine rebuild time! I I am looking to up the performance of my 98'. Now I know the 0331 heads are prone to cracking, but are there any that are better than others? I read in JP Mag that the 95'ish flowed better for a few extra horses on OBD-II engines. Is this true? Any difference between...

In stock form which is the better off road? I know the Grandson have 4 wheel coil and the V8 option. However lack of ground clearance and dep/att angles can offset that. Just a thought going through my brain, I figured I'd ask opinions on.
