# LUBRICATION OF JOINTS GUIDELINES FOR PROPER METHOD

#### VEHICLES AFFECTED: All 1984 Series and 1985 'C' Series Vehicles

Wipe off all dirt from the grease fitting before lubricating the joint. Ball joints should not be lubricated unless their temperature is -12 DEG C (10 DEG F) or higher. During cold weather, the ball joint should be allowed to warmup as necessary before being lubricated. Use a low pressure grease gun on all joints to prevent seal damage.

Steering Tie Rods and 1985 'C' Rear Outer Suspension Adjustment Link (All Models):

Apply grease until grease flows out between seal and tie rod end housing.

Relay Rod (Rear-Wheel-Drive Models):

Apply grease until grease flows out around seal.

Idler Arm (Rear-Wheel-Drive Models):

Apply grease while pushing up and pulling down on the idler arm. (This will prevent 'grease lock'). Apply grease until grease is seen at seal.

Front or Rear Ball Joints (All Models):

Apply grease slowly while watching grease seal. Apply grease until grease is seen bleeding from the seal. If the seal expands but no grease is seen, do not apply any more grease. Allow time for the grease to bleed from the seal. See Fig. 1 for 1985 'C' Series lube fitting locations.

#### All Joints:

Wipe off all excess grease.

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.
