Ball Joint

DESCRIPTION






The ball joint is an integral part of the lower control arm. The ball joint has a non-tapered stud that is clamped and locked into the steering knuckle leg using a pinch bolt. The ball joint stud has a notch formed in the side of it for pinch bolt installation.






The ball joint has a non-vented seal boot. The seal boot has an integrated heat shield.

The ball joint used in the lower control arm of this vehicle is a sealed-for-life ball joint and requires no maintenance lubrication. The ball joint has been lubricated-for-life during the manufacturing process. Once lubricated-for-life, the grease fitting head is snapped off by the manufacturer. This is done to eliminate the possibility of lubrication latter during the ball joints life, thus damaging the non-vented seal boot.

NOTE: The ball joint does not require any type of additional lubrication for the life of the vehicle. No attempt should be made to ever add any lubrication to the lower ball joint.

The ball joint used on this vehicle is replaceable and if found defective can be serviced as a separate component of the lower control arm assembly. Refer to Testing and Inspection for proper testing of the ball joint.

OPERATION
The ball joint is a pivotal joint on the lower control arm that allows the knuckle to move up and down, and turn with ease.
