Shake at speed - ZR-1 Net Registry Forums

Starman · 10-05-2008

Got a bit of a shake at speed on a 91 with 34K miles, just appeared over the last few years. Interested in what others have had issues with. From about 70 mph on, there is a pretty good shake from the rear of the car. Rear spring was replaced last year and the car is adjusted to level. New Nitto tires in May and aligned at that time to spec on a Hunter Laser System - got the print out.

Passes a bounce test fine and no oil on shocks. Seems to be a lot of side to side movement with rear body. I'm curious about experiences with sway bars/bushings, u-joints and other rear suspension items. Getting ready to go through the car and don't want to miss anything.
