Pulsing Vibration in Overdrive
First post here.
Just picked up a 1999 WJ a few months ago. The rig is all stock with a 4.0L and 42Re. On my last long trip I noticed a faint pulsing vibration when in Overdrive only. It mostly occurs when going up hills or accelerating. The vibration seemed to start after I replaced drag link ends, but is coming from the middle/rear end. Can't seem to pin down where the vibration is coming from and it seems to be getting worse. My first thought is transmission mounts, but not sure how to check those.
I've done a bunch of searching and found many threads on this type of problem, but the ones I could find were dealing with lifted WJ's and Wranglers.
Thanks in Advance
