Hey,
I have been hearing that it s common for Z's around the 93 years to have vibrations at high speeds. This is happening to me. I have talked to others about this and have heard that a lot of people who run their camaro's at high speeds put stabalizers on their drive trans... Also done things with their U-joints??
Has anyone heard about these types of vibrations, or is this something else???

Thanks..

 

Driveshaft, what speed?

 

Driveshaft may be out of balance.
U-joints may be crapping out.
Transmission mount could be broke.
Outside of these three, you may have other serious issues.

 

there was a tech bulliten on the stock steel driveshafts and vibration. You could get it replaced for free with an al one but it's probably to late for that.

How much are we talking about? i think between 100-120 when it hits the 2nd harmonic of the nat freq your gonna get a lil no matter what, not car shaking but just enough to feel it, your goin pretty damn fast at that point.
