FRONT AXLE GROWL NOISE NEW PARTS MAY REPAIR

Model and Year: 1983-88 Tl TRUCKS

TO ALL CHEVROLET DEALERS:

Beginning with start of production 1989, the material in the thrust washers in the front axle tube of T Model Trucks was changed to reduce thrust washer wear. The washers involved are #7, #20 and #24 as shown in Figure #1. When worn, the metal in the washer will be smeared from slipping. Number 24 may also be dished.

Whenever it is determined that one washer is worn, all three thrust washers should be replaced with kit P/N 26018721, that contains all three thrust washers.

Parts are currently available from GMSPO.

The kit should be used to resolve T Model front axle growl noise conditions.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
