Procedure for removing/fitting the steering column assembly
|
All Saab 900 within the VIN interval:
R2000001-T2027261 (3D/5D)

Certain steering column assemblies have been known to have handling damage and/or suffer from noise, alternatively the steering has been stiff or felt “lifeless” after replacing/fitting. This is due to uneven loads on the steering column assembly.
This can be rectified by carrying out the procedure described in this Service Information. The procedure is also described in Service Manual 6 “Front Assembly, Steering”, section “Steering Column Assembly” under the headings “Removing” and “Fitting” respectively
