Saab 9-5: Suspension
Affects Saab 9-5 · 1999–2003 — about 3K vehicles.
The hazard
On certain vehicles, when changing back and forth between alloy and steel wheels (as for winter tires), rust and other contaminates may build up on the mating surface of the wheel hubs. If this surface is not cleaned between wheel changes, uneven torque forces may cause wheel bolts to fracture. Although this is most likely to happen during wheel change service, it is possible that the bolts may break later while the vehicle is being driven. Correction: Dealer will clean the hub and reinstall the wheel with improved bolts and attached washers that will eliminate the clamping force reduction.
