31 00... Notes on wheel bearing replacement following accident damage

Wheel bearing facts: 

In the event of accidents or driving conditions similar to accidents, shock-like loads to the wheel bearing units can cause slight damage to the bearing track. Despite initial running without noise, with continued use, this results in later noise generation at the wheel bearing.

Procedure: 

The wheel bearing must be replaced on the damaged side of the axle if one or several of the following points apply:

• Visible or noticeable damage to the wheel bearing
• Rolling noises, radial/lateral runout on the wheel bearing
• Permissible tolerance for the wheel alignment is exceeded and no longer adjustable without the exchange of additional components
• Damage, permanent deformation or fractures to:
  • Wheel rims (major damage) and simultaneous negative result for wheel alignment
  • Spring struts, swivel bearings, wheel carriers
  • Wishbones
  • Struts or trailing links or anti-roll bar with this function
  • Body-side screwing/attachment points for wheel guide/control components
  • Track rods
  • Steering box fixtures

This guideline is binding for all accident repairs to BMW, MINI and Rolls-Royce vehicles!
