Hey guys I have a 97 TJ Sahara 4.0 5-speed with 186xxx miles. I installed 4.5 lift almost two years ago (roughly 20k miles) along with an Advance Adapters SYE and Tom Woods drive shaft. Just recently I'm getting a bad drive line vibration from 2nd gear on when I am on the throttle, coasting the vibe is gone. I took the driveshaft out and upon inspection the rear ujoint was questionable at best so I had it replaced, however, I am still experiencing the same issue. What else should I be looking for?
Again, coasting there is no vibration, only when on the throttle. Pinion angle is correct and has not changed since install.
Thanks in advance,
