| Vibration at between 55 and 65 MPH?
I have a problem with my 91 Eldorado TC that seems beyond solving. I have had everything done to the suspension system possible but still get a vibration at between 50 and 65 MPH. The shop I use balances the wheels off the car, and of course they come up as complying with spec, so I wonder if it could be a bent shaft or something like that. I can remember a long time ago that the wheels were balanced on the car but I guess they don't do that any more. It seems as if that method would pick up any out-of -balance conditions that were other than the wheels. I am at a complete loss and would appreciate hearing about others experience with this kind of a problem and listening to their suggestions.
Much obliged. |
