Service Procedure:

Note: Before conducting the procedure, verify that the vehicle may be affected by identifying the VIN.

A. Knuckle Stop Contact Inspection

1. Test-drive at low speed with the steering wheel fully turned to one side to inspect for noise. Repeat with the steering wheel fully turned to the other side.

Note: If no noise occurs, no further procedure is needed. If any contact noise occurs, repair this condition according to the following procedures.

Note: It is not necessary to repair knuckle stops on both sides. Repair only the knuckle stops that cause the contact noise.

Note: If contact marks are found on the knuckle stop or the stop bracket without any contact noise occurring, do not conduct this repair procedure. Repair only the knuckle stops where contact noise originates.
