Greaseable ball joints are now available for service use on 1988 - 1990 C/K trucks as replacements for maintenance-free ball joints.
Service Procedure
Vehicles requiring maintenance free ball joint replacement do not necessarily require replacement of all maintenance free ball joints. However, should vehicle usage result in the need for ball joint replacement, it is recommended that all maintenance-free ball joints be replaced.

* Parts are expected to be available August 24, 1990. All orders will be cancelled until that date. This kit includes 35mm bolts which are 5mm shorter than bolts used in other kits.
** Parts are available in limited quantities. SPO will make every effort to obtain parts. All parts will be placed on 400 control to waive VIP surcharges. However, the part will be shipped premium transportation at dealer's expense. All other order types will be cancelled as incorrectly ordered while the 400 control is in place.
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.
