Hi guys. The rear end of my jeep has been shaking for some time now. I just replaced all tires and rims and yes they r balanced. It starts around 60-70. I'm out of clues

x91j

Anyone??

Did you properly torque the lugnuts in a star pattern. Are the rear shocks trashed?

x91j

all my shocks are good under a year. No i put them on in a star pattern but used a regular lugnut wrench

have you recently lifted it? And are you sure it's the rear? I just fixed a massive death wobble on mine by getting an alignment done...I didn't realize it was out, but it was off 3 inches.

x91j

nope all stock. this has been a problem for a while now no one knows whats wrong with it. guy at a shop said it was my tires so i replaced em it helped alot but it still shakes. not as bad. i know its the back cuz everything in the trunk rattles. i dont feel anything in the steering

check your axle to leaf spring connection.. replace the u bolts. or tighten them

x91j

should i tighten them while they are jacked up or level and if level how would i go about doing that

spahr69

well the way i would do it is probally jacked up so it drops. so you have get the full tighten.... but level will work the same. but just maky sure you keep each side of the u bolt tightend as level as possible. and if you are to do it level. i would still support it with a jack, because if you take the u bolts off that axle is gonna fall.,, but loosen them up to even.. then tighten them to as even as you can get them.

Maybe your drive shaft is bent or a weight fell off...Tj

where would i check for a wieght?

Check to see if your u bolts are torqued down right, and also check you torsion bar, jeep and dodge torsion bars are notorious for going out, i've gone through two already on my 99 xj

x91j

dont mean to sound stupid or anything but what is a tension bar?

x91j

also how can you tell if u have a worn shock?

ZachsXJ

...unless you're talking about a rear sway bar(which some XJs don't have and wouldn't cause his problem if his has one) XJs don't have torsion bars.

shocks? if the ride is bouncy, or if there is fluid leaking from the shock cylinder.

It'd be noticable, they are typically rectangular pieces of steel that are welded onto the driveshaft. if yours is missing one or is severely bent...most likely thats your problem.
