I had what sounds to be the same problem and used the mitch leland bushing to fix -- problem is that it looks like the mitch leland bushing is no longer available (see,

Rennline now makes one -- see
Steering Column Support Bushing - Nylon-Rennline, Inc. that looks quite similar to the mitch leland one (and isn't too expensive), but have no experience with this solution - unclear whether installation of the bearing that proporsche references would be as easy/straightforward as the leland/rennline bushing solution
