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.
DOOR HINGES & LOCKS
The gas tank filler door, the front doors and rear door 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. The door lock cylinders can be lubricated easily with a shot of GM silicone spray No. 1052276 or 1 of the many dry penetrating lubricants commercially available.
PARKING BRAKE LINKAGE
Use chassis grease on the parking brake cable where it contacts the guides, links, levers and pulleys. The grease should be a water resistant one for durability under the vehicle.
Lubricate the throttle body lever, the cable and the accelerator pedal lever (at the support inside the vehicle) with clean engine oil.
TRANSMISSION SHIFT LINKAGE
Lubricate the manual transmission shift linkage with water resistant chassis grease which meets GM specification No. 6031M or equivalent. Automatic transmission shift linkage should be lubricated with clean engine oil.
