Ball Joint: Description and Operation
Lower Ball Joint
LOWER BALL JOINT
DESCRIPTION
The ball joint is an integral part of the lower control arm. The ball joint has a tapered stud that is pressed into the aluminum knuckle. The ball joint
stud is threaded on the end for a retainer nut.
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. A special fitting cap is installed on the fill port. This cap must not be removed and replaced
with a common zirc fitting. The special cap is there 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.
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.
