First, pull the vehicle's
Steering Knuckle away to service and repair the lower ball joint seal boot. Lift the seal boot free from the ball joint with a suitable tool such as a screwdriver. Clean the grease that has collected around the ball joint stem. To protect the
Control Arm from heat, the upward lip of the new sealing boot should protrude outwards from the boot as it's placed. Make certain that the bullet cap crown points up and out as you slip the boot over the ball joint stem. Use your hand to put the sealing boot onto the side of the ball joint. Line Position Installer, Special Tool 6758, across the ring on the outside of the seal boot and push it down firmly on top of the lower control arm until the boot is pushed straight against the top. Exchange the headless grease fitting for a typical zirc-type grease fitter, keeping the other one for a later replacement. It is necessary to lubricate the ball joint before putting the steering knuckle back on, so that venting takes place from the seal as it is filled. Fill the ball joint seal boot with Mopar Multi-Mileage Lube or of the same brand, pushing grease out past the stem. When this happens, keep wiping grease back into the boot until any excess is cleaned up. Remove the standard zirc-type grease fitting and set the ball joint back to using the headless grease fitting which prevents more lubrication.
