Dear Klaus, et. al,
My '02 S80 2.9 w/159kmi developed a shimmy at speeds of 60+mph (after re-balancing and rotating the tires).
The shimmy is apparent at higher speeds, the frequency is speed dependent, the amplitude is cyclical (although not regular, the amplitude is zero to knock-your-fillings-out).
I first thought it was a wheel balance issue, but re-balancing did not cure the issue. It occurs on-throttle as well as off-throttle. The lower control arm bushings were deteriorated and so replaced, ball joints were replaced also, to no avail. The rack (which was replaced with the salvage one 50kmi ago (Volvo had a 95 unit back-order at the time) is a little loose. The CV joints appear ok. The tires have been rotated back to where they were, same condition still presents.
Any thought would be appreciated.
Thanks in advance.
R Stuart
