    Which brand ball joints?

    I've been trying to decide which ball joints I should get for my '90 XJ and the reviews are all over the place: *"get brand X" / "brand X sucks"; "get brand Z" / "brand Z used to be good but now they suck". * My XJ is my DD with some mild off-road use (4.7 stroker, 4" lift, 33" tires), and*I've...

    '90 XJ - Bendix ABS Conversion Questions

    My Bendix ABS has finally given up and I would like to do the conversion to get rid of it once and for all. I've spent the last couple of days searching forums and videos and I'm as confused as ever. My XJ (33" tires, 4" lift) is a daily driver so I would like to go with new/remanufactured...

    Weird overheating issue - runs hotter when heater is on

    I built a stroker motor last summer and my '90 XJ has been running flawlessly. I have a 3 core radiator, high-flow thermostat (with a bleeder hole drilled), high flow water pump, and hood vents, and it has always run at a constant 195 on both temp gauges until recently. I also switched the...

    '90 Bendix ABS swap - 1 thread source?

    I've just about reached my limit on my Bendix ABS system and want to do a conversion. I've searched the threads and found a bunch of info - maybe too much as I am now so overwhelmed I don't know what to do. Is there one good thread that tells: 1. What is the best swap to do 2. Exactly what...

    1990 XJ 4.0 swap - compatibility, goodies, etc.

    My 1990 XJ's engine has lost compression on #6 (30psi) and my oil pressure isn't what it should be, so it's time for a rebuild. I'm looking for a donor engine so I can still drive my XJ if necessary while I build the new motor. From what I have found on this forum, any XJ or ZJ engine through...

    New Wheels - back spacing? offset? IDK

    I'm currently running 31x10.50x15's on my stock 1990 XJ Limited wheels (15" x 7" I think). I am going to switch to 33x12.50x15's - or maybe even 35's - and I know my stock wheels are too narrow. I also want my tires to stick out farther (wider stance) and I don't want to run spacers. What...

    Help! A/C dumping water or passenger floorboard.

    In the last few days, every time I run my A/C on my 1990 XJ, it dumps water on the passenger floorboard - especially when I turn left or accelerate. I would assume that it is condensation that builds up under the passenger dash somewhere and dumps out when I turn or accelerate - but it is a lot...

    Both of my power seats quit working, but they were both working a couple of days ago. According to the fuse diagram, the fuse is #11 and is shared with the power doorlocks. However, the doorlocks are still working. Any suggestions? Thanks!
