No: 57/02/03/NASRef:
Issue: 1
Date: 05/23/03
Steering Column Lubrication
AFFECTED VEHICLE RANGE:
New Range Rover (LM) All
SITUATION:
STEERING COLUMN SQUEAK
A customer may complain of a squeak from the steering column/bulkhead area when turning the steering wheel. The steering column bushing and grommet fit condition is variable, which can result in misalignment.
RESOLUTION:
LUBRICATE STEERING COLUMN GROMMET
A greasing operation has been introduced in manufacturing as an interim solution to the steering column noise. Lubrication of incorrectly aligned grommets will protect against squeaking. New installations should also be lubricated as described below.

REPAIR PROCEDURE
LUBRICATE BUSHING/GROMMET INTERFACE
1. Open the hood for access and locate the grommet and bushing between the chassis bulkhead and secondary bulkhead.
NOTE:
For illustration purposes only, the column is removed from the vehicle in Figure 1.
2. Ensure grommet and column bushing are correctly fitted and that the column bushing is correctly aligned to the grommet. (Figure 1)
3. Apply Krytox spray (LRN100050S) to the interface of the bushing and grommet.
4. Rotate steering wheel fully in both directions to ensure a uniform distribution of lubricant.
5. Verify that the squeak is no longer present.
6. Re-apply as necessary until squeak is eliminated.
