Removal & Installation
Position a jack under the spring seat of the lower control arm, then raise the jack to support the arm.
CAUTIONThe jack MUST remain under the lower control arm, during the removal and installation procedures, to retain the arm and spring positions. Make sure the jack is securely positioned and will not slip or release during the procedure or personal injury may result.
Remove or disconnect the following:
Brake caliper and support it aside using a hanger or wire. Make sure the brake line is not stressed or damaged.
Carefully guide the lower control arm out of the opening in the splash shield using a putty knife. Position a block of wood between the frame and upper control arm to keep the knuckle out of the way.
- Clean the tapered hole in the steering knuckle of any dirt or foreign matter, then check the hole to see if it is out of round, deformed or otherwise damaged. If a problem is found, then knuckle must be replaced.
Install or connect the following:
NOTEWhen installing the cotter pin, never loosen the castle nut to expose the cotter pin hole.
Press the new ball joint (with grease fitting pointing inward) until it bottoms in the control arm using a suitable installation set. Make sure the grease seal is facing inboard.
Grease fitting into the ball joint, if not already installed
Use a grease gun to lubricate the joint until grease appears at the seal.
- Check and adjust the front end alignment, as necessary.
On 4WD vehicles both the upper and lower ball joints are removed in the same manner.
