Hello everyone, I just bought a cherokee xj 95 with a 4.5" rustys lift, around 45mph and above it has a vibration in the floor pretty bad but it is not in the steering wheel which leads me to believe the transmission mount or Ujoints are bad, any suggestions? It does have the transfer case drop down kit installed. tires are 32" bighorns but I dont think it is the tires . Any help on what to check and where to start would be appreciated.

Happy wheeling

Grab the driveshafts and shake them. They should be nice and tight. If not, you're looking at new u-joints.

Push up and down on the transmission. If there's any movement, you should go ahead and replace that mount. Easy to do.

Also take a look at your motor mounts.

Also at 4.5" of lift, you ideally want to get an SYE in there. That will more than likely help your vibes too.

Thanks , guess i will be replacing ujoints and trans mount, both have play. I was thinking about installing a sye , just really need to do some research on how bad it is to install one. Doesnt look to bad

Replacing you bad u-joints and trans mount may take away any vibrations that you have. Sorry I can't help you sye. I have never done that, At least not yet.

Well replace the u-joints and tranny mount and see what good that does. If you still have bad vibes after that, may be time for an SYE. Lemme look up some write ups for you. I know YouTube actually has a lot of good step by step videos but my work blocks it so I can't look that up for you quite yet. I've never done one myself but it doesn't seem all too bad.
