    Ax15 shifter bushings that don't suck

    I've had the AX15 in my XJ for a couple years now. I've changed the bushings twice, and it's time again. First set was some garbage from ebay, 2nd set was Crown Automotive garbage. So my question is: does anyone NOT in China make shifter bushings for the AX15? 2nd part of this question: I...

    Export RHD front driveshaft length

    Anyone know why the front driveshaft on the export XJs are 2" shorter? I'm about to head to the JY to go pull one in a couple days and wanted to confirm that it's true. It would be pretty convenient if it is, since I need a shorter front driveshaft in the front since I swapped to the AX15...

    Help me trick the 98-01 TCM

    I just swapped in an AX-15 in my 98 and I'm looking for a way to fool the TCM to keep the CEL off. Yes, I know that manual ECUs exist, but I want to crack this egg as there isn't a lot of information about it. Here's what I have done: Initially I had codes p0700, p0753, and p0743. That's right...

    Let's clarify the differences in the NP231

    While in the process of converting my AW4 XJ to an AX-15, I found a little snag while moving my transfer case from the 98 AW4 to the 90AX-15. Novak has a very clear description of input shaft lengths: https://www.novak-adapt.com/knowledge/np-nvg-input-gears Stu Olson's site has some info...

    Rear headrests

    Today I learned that you can get headrests on your back seat if you get the seats from an imported XJ. There were 2 of them at Cape Fear pick & pull in Wilmington NC. They also had a -76 J10 (which I pulled many parts from) -87 Grand wagoneer with complete front/rear D44 axles -about 15 XJ's...

    DIY winch bumper too narrow?

    So I bought one of those $149 eBay winch bumpers. It went together no problem and looks awesome. It also came with subframe tie-ins, which I secured with as many bolts as I could. I haven't wheeled with it yet, so I'll have to just see how well it holds up to pulling on with the winch. My issue...

    Gathering 5 speed swap parts, need some help

    1998, 4.0 vehicle. Originally 2wd auto, I swapped it to 4wd auto a few years back and I even rebuilt the AW4 while I was there. I also added a Transgo HD-2 kit. Works perfectly fine, and has for over 20k miles and 4 years. But I have been itching for a 5 speed and they're so incredibly hard to...

    Steering shaft hoot

    Before I go tearing out the steering shaft, does anyone know where to find the replacement parts for the lower shaft boot and bearings? When it gets cold outside, it makes this awful hooting noise. Sounds like a dying owl. Or maybe a walrus with a stomach ache. Some days it even sounds like...

    So I thought I had 3.73 gears

    So my 1998 (4.0, 2wd, Aw4) did not have an axle tag, so I've never really known the rear ratio. I converted it to 4WD in 2017 and instead of swapping the rear end I just counted the number of input vs output turns. I got about 3-3/4 turns on both axle yokes when the tires made a full revolution...

    Steering wheel shenanigans

    Saturday I had to move my old J10. Since I live on a hill, I pretty much had to use 4L. I had the J10 with a tow bar on the front and the xj hooked up to it with my hitch. So a fair amount of stress was seen by the xj, but it did the job. I didn't drive my XJ until this morning on the way into...

    Factory heated seat switch

    I snagged this switch a couple years ago and finally got around to installing it in my 98. I can't remember what year it came from though, but it's at least a 97-01. It seems like the switch doesn't quite fit right. I pulled the ashtray out and tried to pop it in, then noticed 2 little tabs...

    GM minivan air compressor

    As a kid I remember hearing the compressor on my mom's Olds Silhouette kick on when we would load up the back. I got to brainstorming about a small compressor for airing tires back up and thought about the possibility of pulling one of these from a JY. I have an old 2 gal Campbell Hausfield...

    Junkyard spare tire carrier

    Of all the neat spare tire carriers I've seen available, I really haven't seen a viable option for one from the junkyard. At least, that is, from what I've searched over the past 3 or 4 years. I found some like to use a Bronco II carrier, but they're pretty hard to find these days. Same for the...

    Delayed 2-3 shift

    Let's see if anyone else has fixed this issue before. And before you go commenting on what fixed yours, read the list of things I've already done. 1998 Sport 4.0 4WD AW4 335,xxx miles I bought this in 2014 with 230,xxx miles on it and it's had this issue since I bought it. Under normal...

    KJ rear disc brake lines

    After finally finding a decent swap candidate in my local pick n pull, I got the stuff to do a rear disc conversion on my 98 XJ. For $65, I got both sides' worth of backing plates, calipers, rotors, parking brake cables, and brake lines. I used this write-up...

    P0121 during deceleration

    I see that the P0121 is a common issue with the 4.0, and often erroneously replaced. I hate replacing parts without diagnosis first, so I will not just throw a TPS at it in hopes of fixing it. I have an ELM327 Bluetooth scanner that shows it at 12.5% key on/engine off and at idle. At wide open...

    Strange bump steer

    98 sport, 4wd stock height I recently developed a death wobble, and subsequently fixed it by replacing the drag link (from Pittman arm to passenger knuckle). I also replaced the steering damper since it was damaged. After replacing the worn components, I aligned it in the driveway, test drive...

    Interior lights staying on

    98 4 door sport Through my search, this seems to be a common problem... and commonly never solved. So far I have unplugged the headlight switch, all 4 door switches (the rear ones are hard to get to, as you have to remove the front seatbelts) and the rear hatch main harness connector. Both...

    AW4 output shaft compatibility

    Simple question: Is the output shaft of the 4wd AWD able to be swapped in a 2wd transmission? I understand that I will have to completely disassemble the transmission to do this, which I'm comfortable with. I just don't want to dive in and try it out, only to find out that there's something...

    Engine rattle finally solved

    I figured I would share this here so hopefully it may help someone some day. Let's get some facts straight about knocking/rattling noises! - A rod knocking will get louder and faster as the engine speed increases. It does not go away, and is destructive. It is rhythmic at engine speed. -...
