Rear of my '90 seems to swing sideways slightly
Even on light acceleration the rear seems to lurch sideways slightly, then snaps back when I let off the gas. The tires don't slide, just the body moves. It feels like fishtailing but the tires don't break loose. At first I thought I had a low tire but the pressure is correct. There is no noise involved. All the U joints are snug. I get some slop on one side while rocking the wheel top to bottom with the car jacked up. I can't locate any loose suspension components. The bushings look okay.
Could the differential cause this? Anyone familiar with this behavior? Any suggestions? It has 130K miles.
Thanks
Bill

Not necessarliy the C-beam bolts.
After chasing this behavoir for the past two years I'm convinced it's an alignment issue. Happens during both accelleration and decelleration.
Maybe someday......

The answer is the toe-link in the rear has worn tie rod ends. If it kicks left at throttle on and right at throttle lift, then it's the toe-link worn allowing the rear wheels to steer.
I'm about to price the part from VB&P.

When my rear toe rod assy came completely loose from the diff, this is exactly how the car acted. Check those rear toe rods.
Double check the u-joints too. I had similar symptons when the joint that is tucked inside the knuckle (outboard joint of the axel shaft) broke.
