Upper Front Suspension Arm Ball Joint

The upper ball joint forms the top pivot between the front upper suspension arm and the wheel knuckle, holding the top of the knuckle in location while allowing it to steer and to articulate through suspension travel. Wear at this joint typically presents as steering play, uneven tyre wear or knocking from the front suspension.

Supplied as a service kit including the retaining circlip, so the joint can be renewed in the existing upper arm rather than replacing the complete arm assembly.

Two joints are fitted per vehicle, one per side.

Frequently asked questions

What is the RBK500170 upper suspension arm ball joint for?

The RBK500170 is the ball joint for the upper front suspension arm on the Discovery 3, Discovery 4, and Range Rover Sport L320. It's the pivoting joint at the top of the hub that lets the wheel steer and move. It comes with the circlip service kit.

How many upper ball joints are needed and what's included?

Two RBK500170 ball joints are used per vehicle, one per side, on the Discovery 3, Discovery 4, and Range Rover Sport L320. Each includes the circlip as a service kit. Replacing both together is normal since they wear at a similar rate.

What are the signs the upper arm ball joint is worn?

A worn upper suspension arm ball joint on the Discovery 3, Discovery 4, or Range Rover Sport L320 typically knocks over bumps and gives vague steering as play develops. On the Discovery 3 it fits from VIN 9A000001. Replacing the joint restores tight suspension geometry.
