- AD1: DETERMINE THE SOURCE OF THE INTERIOR NOISE WHILE DRIVING
- While an assistant drives, use a stethoscope (or similar tool) to determine if the noise is coming from the steering column area or other interior components.
- Is the noise coming from the steering column?
Yes No Go to AD2. RE-EVALUATE the customer concern, or REFER to Noise, Vibration And Harshness for further NVH diagnosis.
- AD2: CHECK THE STEERING COLUMN SHROUDS
- Remove the steering column shrouds. Refer to Interior Trim And Ornamentation .
- With the vehicle stationary, rotate the steering wheel to the left and right steering stops.
- Is the noise present while turning the steering wheel?
Yes No Go to AD3. The steering column shrouds may be the noise source.
INSPECT the shrouds for witness marks, proper alignment or damage. REPAIR or INSTALL new as necessary.

Yes No Components may pass a visual inspection but could still be making internal noises. REFER to the list of components in the pinpoint test step and, using a stethoscope, IDENTIFY components with internal noise. REPAIR or INSTALL new components as necessary. REPAIR or INSTALL new any components as necessary.
