32 00... Information on replacement of steering gear/steering column/steering shaft following accident damage

Situation: 

In the event of accidents or driving conditions similar to accidents, shock-like loads can cause different types of damage to steering boxes. When a steering box is externally undamaged, it is sometimes only possible to identify damage with great difficulty and with great effort. However, damage of this nature poses an unacceptable risk to the vehicle because it can result in failure of the steering system.

Because of the disproportionate amount of effort involved, it is generally not sensible to check thoroughly all the individual components of the steering box and as an alternative it is necessary to take into account other components which can be checked more easily.

Procedure: 

The steering box must be replaced if one or more of the following points apply:

1. Visible or noticeable damage to the steering box
   • Version with electric steering box (EPS): Examine in particular the control unit with all plug connections for damage and hairline cracks.
2. Unacceptable torque increase and jamming when the steering box is turned from lock to lock (without hydraulic/electrical assistance)
3. Permissible tolerances exceeded during axle/wheel alignment (include alignment record with invoice/report if necessary)
4. Fire damage
5. Damage, permanent deformation or fractures to:

• Wheel rims in the event of a negative result from the wheel alignment check
• Spring struts, steering stubs, wheel carriers
• Control arms
• Struts or trailing links or anti-roll bar with this function
• Body-side attachment points for wheel guide/control components
• Front axle support
• Pitman arms
• Track rods
• Steering box fixtures
• Steering Column

This guideline is binding for all accident repairs to BMW and MINI vehicles.
