So I have had my 2.5" rough country lift on since January and in about June my jeep death wobbled once but didn't think anything of it because it only happened once. Well lately it has been happening very violently and I took it to a shop, they drove it, and then saw my front drive shaft was bent and they replaced that. but the day after I got it back it was doing it again. I really would like to get this fixed but I have no idea what it is. I have checked the basic thing like tire balance, it has a brand new steering stabilizer, everything is greased, and everything is as tight as its gonna get. I just have no idea what it could be, it makes me even more mad that I wasted almost $1000 dollars on a front drive shaft that was barely bent and it didn't even fix the problem. Please help
it's $300 tops for a brand new unit, and removal/installation is 5 minutes and only 8 bolts. you can install/remove a front shaft on the side of the street with a single open ended wrench - i've done it before.
on top of that, the front driveshaft has absolutely nothing to do with your DW.
something is worn out in the steering system and/or the alignment is bad. check everything...track bar, tire balance, ball joints, unit bearings, control arm bushings, TRE's, etc. identify whats bad and replace it, then get an alignment to make sure caster/toe is good.
Sorry to say, but that place wasted your time and money. You need to check basically everything that is on the front axle. ANY amount of play is no good, you can have 1 thing or a combination of things. Control arm bushings seem to be always over looked. Everyone always thinks track bar and steering stabilizer. CHECK EVERYTHING! If you check your stabilizer, take it off and cycle it by hand, all the way in and out.
$1000 or $800 = too much. From Tom Woods website about front shafts for TJs:
"For the Double Cardan (CV) drive shaft we have two options available. Upgraded heavy wall tube larger/stronger slip yoke & spline stub (S spline) @ $269 or the top of the line shaft with the longer travel slip & spline (XC OR XB spline, see sidebar at bottom of page) for $299. Of course, these would be built with our “Gold-Seal” universal joints. For long term value, We consider the top of the line shaft to be the best value."
I wouldn't trust whomever did the $1000 front shaft on your TJ.
I don't know if that would narrow it down any but the track bar moves slightly when the steering wheel is turned
There's most likely your problem, or at least part of it. Check both ends of the track bar for movement. Sometimes the ball joint on the drivers side fails, but usually its the passenger (axle) side. If the bushing is good on that end, see if the bolt hole in the axle bracket is wallowed out
