1983 280ZX Turbo ; floating on highway

Also glad the problem was solved. Not knowing what the first mechanic was doing or not doing I will give him a little slack. The floating description meant to me that the front of the vehicle was getting light and effecting the steering. I would never have thought about oscillation at the rear of vehicle.

A bent axle flange or hub will cause a vibration, did you notice a vibration? I donā€™t see how this can cause a soft and floating ride, I can understand why there was much focus on the shocks and struts with a complaint about a soft ride.
