Chassis Greasing

Print

See Figures 1 and 2

The front suspension and steering linkage should be greased every 12 months or 7,500 miles (12,000 km) with an EP grease meeting GM specification 6031M.

If you choose to do this job yourself, you will need to purchase a hand operated grease gun, if you do not own one already, and a long flexible extension hose to reach the various grease fittings. You will also need a cartridge of the appropriate grease.

Press the fitting of the grease gun hose onto the grease fitting of the suspension or steering linkage component. Pump a few shots of grease into the fitting, until the rubber boot on the joint begins to expand, indicating that the joint is full. Remove the gun from the fitting. Be careful not to overfill the joints, which will rupture the rubber boots, allowing the entry of dirt. You can keep the grease fittings clean by covering them with a small square of tin foil.
