So I've been having this weird symptom for a while now and it's time I try to figure out what is going on. Whenever the auxiliary (electric) fan starts to run, the voltage gauge on the dash dips and if my head lights are on they momentarily dim. Is this a sign the alternator is failing, or...

So now that the warm weather is here, my A/C doesn't seem to be working very well. On warm days it works a little, but on really hot days it doesn't work at all. Any suggestions as to where I should start my troubleshooting? Thanks! Edit: forgot to mention it's a 99, 4.0L, auto.

First off, I checked some other threads and none seem to have to the problem I am having. I pulled a set of leather power heated seats from a wrecked '00 limited. They worked fine before I pulled them. From what I read in other threads it's a pretty straight forward swap. I connected the...

Behind not allowing posts to be edited after a certain time period? This is the only forum I have ever seen that does this. It makes it difficult to update the first post with new information relating to troubleshooting etc. It would be nice, if I were working on a problem for a while, to be...

So a problem developed last night with the idle of my 99 XJ, 4.0L, AW4 with ~106k miles. While in drive, when I take my foot off the gas at any speed it idles at around 1100-1250RPM. Normally it would go down to 750ish RPM. It won't drop down to the normal 700-750RPM until I come to a...

What kinds of things should I be stripping from it? The engine runs and is already sold. I'm grabbing the power leather seats, cruise control, pw assemblies and I'd like to keep the transmission and xfer case for spares. What else should I be keeping?

Does anyone know if they are the same for either of these xfer cases?

I'm going to look at a parts XJ (2000) tomorrow that was was flipped onto it's roof. Other making sure there is enough oil in the crankcase, is there anything I should be checking before trying to start it up?

So for the last couple of days I've been noticing that until the engine is good and warmed up the alternator output will drop to around 11V when I come to a stop (idling at a stop light etc). Eventually it stops dropping down and keeps a constant 14V. I've also noticed a little bit of...

First off let me say that I've done a ton of searching and can't find an answer to my questions. I am primarily after some answers to questions but I also thought it would be a good idea to amalgamate some of the many links I have come across to help anyone who tries to do this in the future...

So I have a set of the quadratec HD rear springs that I want to put on my XJ to replace the sagging ones. From what I've read you end up with 1-2" over stock height. I also read somewhere that you can use ZJ coils in the front to get ~1" of lift. Every post says to use the V8 coils. I am...

Does anyone know where I can get the support brackets for the bumper mounted tire carrier? I bought one from a wrecker and had it shipped to me but they didn’t include the brackets and insist they weren’t on the Jeep. I’m looking for the brackets that tie it into the unibody. I can probably...

I found a decent deal on a set of power leather seats from a 91 XJ that I was thinking about putting in my 99. Does anyone know how much trouble this would be? I've been told they are not a direct bolt in. TIA!

I bought a 99 XJ a month ago and ever since I got it there has been a vibration. It usually starts around 55MPH but the weird thing is that sometimes it’s not there and I can go up to 70MPH without noticing it. Sometimes getting off the gas and back on will start it, other times if it’s there...

Hi, I've found a pretty good deal on a set of 16" Rubicon Rims (5" BS) and I was thinking of putting them on my 99 XJ with 245/75R16 tires (30.5 x 9.8"). Is anyone else running this type of set-up? Will I run into any rubbing issues under normal driving conditions (not off-road)? Also, do...

So I just bought a 99 4-door sport and the day after I got it I noticed smoke coming from the front passenger side of the vehicle. The brake rotor dust sheild was bent and touching the rubber that holds the grease in the tie rod (or drag link?) end, which it melted through and the grease that...
