Upper and lower ball joints (four in all) the pitman arm, and the tie-rod ends (four) require greasing every three years or 30,000 miles. Halve that interval for cars driven regularly over unpaved back roads or used for other severe service. You'll need a cartridge of #2 chassis lubricant rated EP and a hand grease gun.
- Jack up the front of the car and support it at the lower control arms with jack stands.
- Locate the grease fittings and wipe them clean.
- Push the grease gun over the grease fitting and pump the lubricant in until grease flows freely from the bottom of the seal or when the seal begins to balloon.
- Wipe off any excess grease and lower the car.
