replaced clutch, new vibration at 45+ mph
 

The clutch was replaced by a pro shop. Vibration was instantly apparant. I
thought the clutch itself was the casue, but that clutch turned out to have
other issues and was replaced again under warranty. The vibration stayed. It
is strictly speed related, not RPM's... you can push the clutch in and it's
still there.

My mechanic said he shot a bunch of grease into the driveline and that it might
now be out of balance from that... you think?

Did they replace the pilot bushing? Did they resurface the fly wheel? How
is you harmonic balincer?

Re: replaced clutch, new vibration at 45+ mph
 

Grease moves as your 'mechanic' well knows so it sure won't be killing
the balance by lubing something and for him to suggest such --------
isn't a good sign.

Did he take apart the driveshaft to maybe clean it before greasing it?
If so maybe he put it back together out of phase. This can cause a
vibration. In phase just means if the front u-joint cap with the bolt
is at the top, then the rear needs to be at the top too, not at the
side.

Did a u-joint just decide to up and quit because it didn't like having
the caps removed? Did he drop or break any needle bearings in the
u-joint? (that would be my guess seeing his trying to baffle you with
BS attitude)

Did he break one of the yoke tabs so the u-joint isn't seated square.

Did he forget to tighten up the u-joint or maybe the tranny mount?

He did something wrong.

Mike,
you are right the drive shaft. That is what it sounded like to me. Watch
out for those shade tree mechanics.
