Every 12 months or 7,500 miles (12,000 km), the various linkages and hinges on the chassis and body should be lubricated, as follows:
TRANSAXLE SHIFT LINKAGE
Lubricate the manual transaxle shift linkage contact points with the EP grease used for chassis greasing, which should meet G.M. specification 6031M. The automatic transaxle linkage should be lubricated with clean engine oil.
HOOD LATCH & HINGES
Clean the latch surfaces and apply clean engine oil to the latch pilot bolts and the spring anchor. Use the engine oil to lubricate the hood hinges as well. Use a chassis grease to lubricate all the pivot points in the latch release mechanism.
The gas tank filler door, car door, and rear hatch or trunk lid hinges should be wiped clean and lubricated with clean engine oil. Silicone spray also works well on these parts, but must be applied more often. Use engine oil to lubricate the trunk or hatch lock mechanism and the lock bolt and striker. The door lock cylinders can be lubricated easily with a shot of silicone spray or one of the many dry penetrating lubricants commercially available.
PARKING BRAKE LINKAGE
Do NOT lubricate the parking brake cables. Lubrication destroys the plastic coating on the cables.
Use chassis grease on the parking brake cable guides where they contact the links, levers, and pulleys. The grease should be a water resistant one for durability under the car.
Lubricate the carburetor stud, carburetor lever, and the accelerator pedal lever at the support inside the car with clean engine oil.
