Stabilizer Bar (Front) - Noise/Rattle

GMC NUMBER:

87-T-60

GROUP:

3C - Front Suspension

DATE:

June, 1987

CORPORATE
NUMBER:

763301

SUBJECT:

FRONT STABILIZER BAR INSULATORS

MODELS:

1985-87 C AND R 1,2,3 MODELS EQUIPPED WITH RPO F59 FRONT SUSPENSION

Some C and R model trucks with loose or missing front stabilizer bar insulators may produce a noticeable noise or rattle as the vehicles are driven. On
those vehicles found missing the outside insulators, a new nonsplit insulator should be installed at the lower control arm attachment point of the stabilizer
bar. The
new nonsplit insulator, P/N 3995334, requires retaining clamp P/N 3978931 when installed. The new nonsplit insulator should be used whenever the
outside insulators are replaced. The center stabilizer attachments continue to use the split insulators called out in the parts book.
