That and the track bar. The arms keep the axle's castor and pinion angle lined up. The longer the arms, the more radius travel the axle will have by decreasing the rate of working angle. The shorter the arms, the 'faster' the angle will change under flex and articulation. The track bar keeps everything lined up horizontally, as coils just float on isolator posts on the body as opposed to being bolted at two points like leafs. e: That looks like the TnT Customs Y-link setup which I plan on getting here in a few weeks (actually it's Rough Country's knock-off). TnT's is the only one I've seen that offers an actual skidplate that protects worth a drat (trans and t-case) instead of being some simple crossmember with arm mounts. Plus it gives you an extra inch of ground clearance. Philip J Fry fucked around with this message at 01:52 on Jun 3, 2011 |

I haven't seen a YJ soft top up close in a while, the zippers for the windows, right? I can't imagine snaps working nearly as well as zippers. Plenty of people swear by graphite for lubing zippers. Perhaps give that a try instead?

They lose teeth all the time and one of them fell apart. I can't imagine snaps failing nearly as bad as that. also, I'm thinking about adding snaps to hold the windows down to the body (the weatherstrip/channel thing doesnt work that great under wind) and to replace the worn velcro bits around the door.

A little light on pictures, but it'll show you how to do just about any repair you need to do. to be technical, I have an old model Bestop Supertop. The passenger side window is the one that is most messed up. The tension rod that runs parallel to the rollbar tends to put a lot of stress on one part of the zipper which causes it to split. I'll get some pics of what I'm trying to do.

In reference to the pics above, after talking it over with my father and looking at all the parts and stuff, We've come to a few conclusion. The fluid in the cylinders is my excessive PB Blaster that I was spraying everywhere to ensure no bolts got stuck. I wasn't sure if it was coolant or not. On the drivers side of the head (right in the pictures), the coolant passages are clogged solid. The troubling thing is, the headgasket is solid. I haven't done my full fledged research on everything, but that may or may not be an issue. I'm trying to understand what failed and why. The headgasket looked okay and there seemed to be little cross contamination. There was that one valve area at picture #5 that looks pretty burnt up. Also, the pistons in the block have a bit of play. You can wiggle them in the block to an estimated 1mm or so. That and the block has no crosshatching anymore. Trying to figure out what my best course of action is at this point. Have the heads checked by the machine shop and rebuild it with new gaskets, do the piston rings and bearings while I've got things apart, or go nuts and get some 258 parts to make a poor mans stroker. A bit too early to be starting a project, I should still be figuring out what's good and what isn't at this point, then go from there.

Well, went and picked up the '92 XJ Sport tonight. Had driven it around the neighborhood where the seller lived, since it wasn't plated at the time. No issues. Got to their place, topped off the oil w/ 10W-40, topped the coolant. Drove home - about 110mi, 70 of which are highway. Noticed that it was downshifting (its the AW4 auto trans) out of overdrive often around 65mph. Would jump in and out of OD. Got to a light about 5 min from home, it stalled when coming to a quick stop. Great. Rest of the way home, felt like it was dropping out of gear, or maybe shifting really sluggishly. Vibration. Pulled into the driveway - had a hot friction smell on popping the hood. A little like clutch or brakes, maybe. Whole way home, oil pressure was solid, temp was good. Transmission fluid level appeared to be good but the color was not the red I was expecting - was more like a clean motor oil color. Hoping to pick up new AT fluid and flush it immediately tomorrow morning. Hope to god the trans isn't going. It only has 100k on it. tl;dr: Bought a 92 XJ sport, 4.0L auto 4dr 4wd w/ 100k and clean carfax w/ maintenance records for $1500 - transmission is acting up

I can't speak for the 92', but I know my 88' XJ with the 4.0L had lots of strange stalling issues that I ended up tracing back to torn or broken vacuum lines. That may be a good place to start - your transmission issues may also stem from the same place. e: Also, as a side note, I have a 4.0L with 60k miles and a 5 speed tranny with 30k on it from a 93' 4WD Grand Cherokee that I'm getting rid of. If anyone is interested, let me know

I need to do mine badly as they cause a bit of this, but I crawled under there today and it seems like my passenger side u-joint has some play to it when I push/pull on it. Driver's side seems ok. Today it started clicking real faintly which I understand is probably also from the bad u-joint. Just one more thing to add to my to-do list I guess. It keeps getting more expensive and I am having a hard time keeping up with it financially. - coil spacers, add-a-leaf lift & new shocks - cracked exhaust manifold - front end bushings - cooling system flush - O2 sensors [P0138] - u-joints

Welp, coolant/oil done. Partial AT flush done. New sparkplugs (wish I had gotten a picture of the ones I pulled - they were toast). Broke the heater valve. Replaced that. Fixed the issue with it not coming out of 4-high to 2 again. Diagnostic lights still not working on dash. Have to figure that one out - wasn't the fuse. Must've been the PO's installation of a aftermarket headunit that hosed something up. New liftgate struts are on order. Took it out on some relatively tame trails for babby's first 4WD. Transmission problems seem to have subsided. So it begins.

Iron Squid posted:It'll be like every relationship I'm in. EDIT: The short answer is that most of the mechanicals evolved from longitudinally-mounted RWD kit, and so the additional takoff is the one to the front, and this is what's switchable. Effectively they've just taken a slice out of a RWD transmission, taken an output to drive the front axle, and put an on/off switch on it.

Well damnit, the AW4 acted up again while cold. Looks like its headed to a mechanic on Wednesday for a once-over. Still haven't figured out what the PO did to kill all the idiot lights during the headunit install. The 4.0L HO engine has some balls, though.
