'79 Corvette sways while driving
My 1979 Corvette while I am driving 30 mph and up (cruising and accelerating)sways to the left and right. I do know it is coming from the rear end. I have heard that the bushings from the arms that are holding the read axle is bad and needs to be replaced with polyurethane bushings. Do you think this is the primary reason or can there be another issue? Is there a test that I can do to see if the bushings are bad?
