So I took my 97 into the shop to have the alignment checked today. The back of the car has started to feel like it is steering on its own, especially at highway speeds. They told me the rear toe compensation links are shot. They want $250 to replace the pair. How hard are these to replace? I only find brief mention of them from searching on this site and can only find 2 places online that even sell them. Do you think that would cause the rear of my car to squirm and wobble on the freeway?
