Driveline Vibration

[NCtaco]

Has anyone had any driveline vibration?

I seem to have developed some weird vibration under hard acceleration and when coasting in gear.

Any ideas?

sounds like a worn out U-joint in the driveshaft or the carrier bearing in the center of the shaft

Mine turned out not to be in the driveline at all. It was the idler pully and I hear it's common. Worth looking at anyway.

Start with the simple stuff. Been in the mud? Clean your rims; they get filled with dirt easily. Then, look for missing wheel weights or a bent rim. If it gets worse under acceleration it's probably in the drive shaft.

After finally finding the squealing issue, which was a very thirsty drive shaft bearing.  We discovered that it is one or both of the rear tires or rims.

Thanks for the ideas.
