1990 80 Quattro Steering/Handling Question

[Turse, Thomas (CORP, GEAccess)]

Hey All,

Just wondering about my 80Q handling- steering feels kind of loose and
wobbly- especially at higher speeds- above 65 mph.  I had all strut
cartridges and strut bearings replaced and had new stock size tires
installed.  Reputable shop did the 4 wheel align and tire balance and they
said everything was tight and bushings were ok.  The car is much less stable
than my old 85 4kQ with less than new struts and a few weak bushings.  Any
thoughts would be very much appreciated.  Also, anyone know if anyone has
the procedure for replacing the air filter for 80/90Q's?

Regards,
