Vibration while accelerating

[bgrabaum]

I have a 97 TJ 4.0 with a manual trans

I was driving and went around a corner then put it into second gear to accelerate and had my rear driveshaft pop from the furthest rear u-joint. I later replaced the u-joint and got everything back together only to find that I now have a shake when accelerating at any speed above about 35. As soon as I let off the gas the shake is gone. Any ideas as to what could be wrong?

I would remove the driveshaft again and inspect/ replace the other U-joint. Also if you dented the tube anywhere using a hammer it's now out of balance.

If you are unsure, drop it off at a driveline shop and have it inspected and balanced.

Okay thanks for the advice. That was my thought as well
