Hey everybody. I recently purchased a rustys 3 inch lift for my 96 xj. I hav been insatlling it over the last few days, and i have a question.
After installing the new coils infrt and new leaf packs in the rear I now have developed a real bad vibration and binding out of the rear diff. I asked several different compaines including rustys if I needed to do anything else. Like a t/c drop or dropped pitman and was told no.
Does anyone know what i can do now to eliminate the binding short of having to buy a t/c drop kit. Any help would be great. thanks

 

Steel shims for rear leafs at 4 deg. RE sells them. You should actually do an SYE to your transfer case though. Shims and TC drops are bandade fixes.

 

A TC drop kit will help your vibes. The 96+ XJs have a shorter output then 95 and older. Therefore they are more suceptible to vibes from a shorter amount of lift. I guarantee you that a 1 inch TC drop will cure your vibes or at least greatly reduce them. If the TC drop doesn't fully eliminate your vibes then add a 3-4 degree shim to your rear axle and that will do it. I'm running a 1.25" TC drop and 6 degree shim in my 91 XJ with 6 inch lift and I have had no vibes for 2 years with this set up. Because I'm to cheap to buy a SYE kit. I know this will last me until I can build a SYE.

 

possibly shim the rear end. what are you drive angles lookin like? i put in a 1" t-case drop and shimmed the rear and i still have vibes. mine is a 2000 w a 4.5" lift

 

Before you go shimming anything you need to measure your pinion angle. If your pinion angle is way off you can add shims, if it's not off by at least 2* shims will not help. If the pinion angle is accurate ie less then 2* off then you have 2 choices, SYE the best way or a t-case drop which isn't the ideal solution but it works.

 

OKC is correct. I would look into shims before a T-case drop just cause its a more effective solution i mean you lifted it for a reason. Good luck and keep us updated.
