Prewinter chassis lubrication is wise to protect steering and suspension ball joints from Cold and road splash. Refer to the service manual for a lubrication Chart that indicates grease fitting locations. If you don't have a manual, check each pivot point of the suspension and steering network for fittings.
Wipe grease fitting clean and attach a hand grease gun filled with chassis grease. You may wish to use a gun that accepts cartridges of grease This tool is similar to a caulking gun and has the advantage of being less messy to use than a grease gun you fill from a bulk container.
Pump In grease until grease oozes from the bleed hole in the base of the ball joint seal or until the seal begins to swell.
After tubing, wipe the fittings clean again and replace rubber plugs over the fitting. It your fittings didn't come equipped with rubber plugs, you can purchase a set easily.
To complete the lubrication phase of winterization check and replenish these fluids:
Brake fluid
Automatic transmission fluid
Rear-end oil
To keep the doors, trunk lid and hood from getting creaky in the cold, spread grease on the hinges. You should also lubricate the door handles lightly. However, don't use grease in the locks. The best thing to use there is graphite powder to keep the lock mechanism functional. If locks do freeze, squirt lust enough deicer on them to free them. Don't allow too much to get into the mechanism.
