Chassis greasing can be performed with a pressurized grease gun or it can be performed at home using a hand-operated grease gun. Wipe the fittings clean before greasing, in order to prevent the possibility of forcing any dirt into the component. Fill the ball joint or tie rod end with grease until the seal starts to swell. When the lubrication operation is complete, wipe off any excess grease.
Ball joint and steering linkages are semi-permanently lubricated at the factory with a special grease. They should be greased every 15,000 miles (24,000 km) or 18 months, whichever comes first. When greasing is necessary, use only special long life chassis grease such as Mopar, Multi-Mileage Lube or its equivalent.
