Condition
Some owners may comment on front suspension noise. The noise may be described as a "bong" or "clunk" noise. The noise may be more noticeable when driving slowly over bumps or backing the vehicle out of a driveway.
Cause
The front coil spring contacting the frame may cause this condition.
Correction
A new front coil spring insulator has been developed to correct this condition. Install a new insulator (1) to the top of both front coil springs. Refer to the Front Suspension subsection of the appropriate Silverado and Sierra Service Manual for coil spring removal/installation procedures.
This new insulator replaces any existing coil spring insulators. Remove and discard the existing insulator before installing the new insulator. Use the part number listed below.
