Description

Lower Ball Joint – Front Hub for the front axle steering knuckle (swivel housing) assembly.

The knuckle pivots on an upper and a lower ball joint; this lower joint forms the bottom pivot point that lets the front wheel assembly swivel for steering while carrying suspension and braking loads. It is a common wear item – play here causes steering wander, knock over bumps and uneven tyre wear, and the joints are usually renewed in pairs with the upper joint FTC3570.
