[s-cars] drive shaft, knocking or vibration?

[Dave Burig]

Serge,
At WOT, the noise is drowned out by the beautiful cacophony of induction
noise, turbo whine, screaming children, giggles, wife kvetching.  Most
noticeable under partial throttle (Go ahead Paul, insert "What's that?"
comment here;_________hellf'nhairyass________Muwahahahahaha______).
The noise is really not noticeable (can't be heard?)after about 4K RPM.

Dave

Dave, is the noise louder at WOT (as you smack the redline in 1st gear) than
if apply the throttle in a more gentle fashion? If the noise is "load
dependent" then you most likely have a CV joint issue (on the prop shaft or
otherwise). There is a slight "pulsing" that comes with this noise, and a
mild vibration.


Drop the prop shaft and regrease those dried out CV joints.
