Customers may comment about a "loose lumber" noise from the front of their vehicle, especially while travelling over rough roads at low speed. Application of the brake will eliminate the noise.

This condition may be corrected by installing new caliper mounting bolt assemblies, P/N 18017373, following the procedures in section 5B-2 of the Service Manual. These new bolt assemblies have a larger outside diameter sleeve.

Parts are currently available from GMSPO.
