Some 'E' and 'K' series vehicles may experience torn or worn drive axle boots commonly diagnosed as a leak under the front of the car or a squeak in the front end. This condition, which is more prevalent at high ambient temperatures, may result from the drive axle grease inside the axle boot reacting with the boot material over a prolonged period of time. In mid-February of 1983, a new grease was released for production. All WDDGM stock of drive axle boots currently includes the new grease; the part numbers for the drive axle service parts remained the same. Part numbers for the grease kits containing the new grease for the iboard and outboard seals are as follows:
GREASE SERVICE KIT P/N --- --- OuLtboard 7845010 Inboard 7845011
When servicing a drive axle shaft, make certain only new grease is used.
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.
