XJs4Ever Posted November 29, 2009 Share Posted November 29, 2009 Howdy Folks! Been awhile. My $#itty life keeps getting in the way. Hey - With a massive puller, a BFH and a lot of heat, I popped off the pitman arm off my MJ to replace with a ZJ one I've had for years. I had some DW's so I lowered it down to 1" [V-8 ZJ coils] but no change so I replaced the tie rod [left outer end] and that did the trick. Put the 3" coils back on [gain of only 2"] and the DW's are back! I'm waiting on a pair of extended LCA's from a guy whos stood me up 3 times so far but when/if he finally comes thru on those, they're going on too. While its cooling on the garage floor, I set the two arms together, and its hard to tell if its actually longer or if the angles are just sharper. Anyone know? I am pretty sure XJ/MJ arms are the same. The ZJ one is on the right... Image Not Found Link to comment Share on other sites More sharing options...
mvusse Posted November 29, 2009 Share Posted November 29, 2009 Yes, ZJ pitman provide about 1" drop over MJ/XJ ones. No need for this on a 4 link set up like we run, unless it fixes aignment angles between the steering arm and track bar. It also gives the steering box more leverage on the frame, and mine already cracked the frame and started pulling bolts through with the stock pitman arm. DW is not affected by the angle of your steering components, thst just affects bump steer. Possibilities are: play in track bar (usually cause by elongated hole in frame mount) bad bushings allowing play in control arms (especially lower) bad tie rod ends bad ball joints wrong toe in A (better/bigger) steering damper is often sold as the fix-all for DW, but it just masks the symptoms and ignores the underlying cause.

XJs4Ever Posted November 29, 2009 Author Share Posted November 29, 2009 Thanks boss! The toe has been on my mind ever since the front lift went back on [didnt add any to the back yet]. I never adjusted it. I'm draggin the wife out to Awful House for breakfast, then its back here to put the truck back together and set the toe. Also gonna add some longer shackles to the rear to get some forward rake. All I have back there now is an extra XJ leaf for more load capacity. It only gave me 3/4" of lift but I destroyed four bits drilling the centerpin holes. They are smaller than MJ's. Link to comment Share on other sites More sharing options...
mjeff87 Posted November 29, 2009 Share Posted November 29, 2009 I'm draggin the wife out to Awful House for breakfast You got them out there in CO??? I thought they were only a "southern" thing...... I love 'em.....the only way I can get my wife to go in one is if I pay. My mother will NOT step foot in one, though. :cheers: Jeff Link to comment Share on other sites More sharing options...

Secret when drilling steel is SLOW speed on the drill, steady pressure, and lots of oil. Drill press at 250 rpm works great. Link to comment Share on other sites More sharing options...
Pete M Posted November 30, 2009 Share Posted November 30, 2009 I thought someone here had great results with masonry drill bits. :dunno: I had to break out the good bits to drill though mine. :D Hi Rick! :waving: Link to comment Share on other sites More sharing options...
XJs4Ever Posted November 30, 2009 Author Share Posted November 30, 2009 HAW!! Jeff, as always - ya kill me! ;) Cin loves that place. Me - ya I like em cept what they pride theyself on...hash browns. I hate theirs. Okay well the arms on and toe set and yet STILL the DW's persist. 1" lift - no prob. 3" lift - DW's. WTF???!!! Swapped in LCAs and UCAs from a '98 XJ, new tie rod end, alignment, trackbars good n tight, new steering stabilizer....what else?! :mad: I didnt add the shackles. I did the math and it would have only gave me 5/8" lift so I decided it wernt worth the effort. DW's seem to be an MJ thing. I've had two XJs both I lifted over 4" with no DWs ever on either one. Both MJs had them right from the get-go. Tore my 86 to peices! Well I do have a spare used trackbar I have no other path but to swap it in and see what the hell happens. :dunno: Link to comment Share on other sites More sharing options...
Pete M Posted November 30, 2009 Share Posted November 30, 2009 I would check balljoints and wheelbearings next. also, tire imbalance is a known wobble inducer. :thumbsup: Link to comment Share on other sites More sharing options...
XJs4Ever Posted November 30, 2009 Author Share Posted November 30, 2009 Puttin on the spare trackbar now. Will dbl check the control arm bolts n ball joints. May even swap the tires/wheels with the XJ. The toe was only off 1/8" so a 1/16" adj was all I needed. Link to comment Share on other sites More sharing options...

The toe was only off 1/8" so a 1/16" adj was all I needed. Well that didnt do a damn thing either [trackbar swap]. As far as I can tell the ball joints are ok. Plus wouldnt that be a problem at stock height aslo? I can't understand why adding 2" is causing this crap! I guess I'll swap tires/wheels with the XJ & see what happens.

Pete M Posted December 1, 2009 Share Posted December 1, 2009 adding lift changes the geometry of the system and rigs that are prone to DW will be much more sensitive to those changes. picking up DW after a lift is actually pretty common. :( Are your lower control arms matched to the lift height? losing the factory caster can be a tipping point.

Well, I am waiting for a set of extended LCAs from a dude whos in Moab now, BUT my 89 XJ as well as my 91 XJ both had 5" and neither ever suffered from this. I may hit the boneyards for a complete set or steering jazz off a ZJ [tie rods, centerlink, drag, trackbar etc] HEY - ZJ LCAs are pretty beefy...will they fit an MJ? Ours are like C-challel. Those are closed Link to comment Share on other sites More sharing options...

Those are closed HI RICK! :waving: I would shoot for WJ control arms, as they have a little bend in them to help the tire from rubbing. The ZJ/WJ/MJ arms are the same length... But grabbing a good set of stout V8 ZJ linkage might help you out. Make sure all the joints are good though! Glad to see you stop by! :cheers: Rob L.

james750 Posted December 2, 2009 Share Posted December 2, 2009 Hi Rick! I had some nasty wobble issues all summer with the 31" A/T's on the Jeep. But as soon as I swapped my 31'' MT's on the wobbles went away, hopefully your wobble goes away with the XJ tires. Link to comment Share on other sites More sharing options...
navigator Posted December 2, 2009 Share Posted December 2, 2009 funny, i had a set of almost bald 235's on mine with no DW problems. I got some new 235's and occasionally if I hit a hole or something on a dirt road I would get some DW. I tightened up the steering box bolts and a tie rod end and the DW went away. I still have some play in the steering though. I think I need to just replace all the tie rod ends and the track bar and that should fix the play.

Pete M Posted December 2, 2009 Share Posted December 2, 2009 DW is caused/allowed by slop in the front suspension system. this can be a single worn part, or a combination of several semi-worn parts that let the oscillation grow uncontrollably. No two rigs are alike, and DW can be an infuriating problem. :fs1: Link to comment Share on other sites More sharing options...
XJs4Ever Posted December 3, 2009 Author Share Posted December 3, 2009 I dunno guys. I am out of parts to check/replace. I will swap tires/wheels tomorrow. Hey James did you ever instal the gas strut with the mounts I gave ya? Thats my favorite Jeep mod - gettin rid of the prop rod! Thanks Rob/Phil/Pete/everyone for the advice. I just thought of a smilie this thread needs - a smilie beating on a dead horse.... Link to comment Share on other sites More sharing options...

Hey James did you ever install the gas strut with the mounts I gave ya? Thats my favorite Jeep mod - gettin rid of the prop rod! Yeah, I mounted it a few days after you gave them to me, I only needed one of the mounts because the XJ hatch strut I used had a good mount already on the other side. I showed it to my dad, and now he wants me to install the other one on his XJ! I plan on doing that during its next oil change. Thanks again for the mounts! :thumbsup: Link to comment Share on other sites More sharing options...
