Well, just got them swapped and took it for a test drive. It appears to have made NO difference in the vibration/hopping feeling that I get under acceleration and any speed above 50. It seems to get worse when accel. and then subsides a bit when I let off and coast. The only other thing I can think of now is that I have a CV axle going bad. Neither of them have any torn boots or are leaking, but I did notice that I could get a bit of play on the pass side when I grab the half shaft and push down. Get a bit of a clunk from the inner joint. Could this be causing this horrible vibration/hop?
I guess I'll get it on jackstands and see if the thing wobbles under accel. Kinda running out of ideas here.
