Frequently asked questions

What does the steering box race bearing do?
This race bearing carries the worm shaft inside the recirculating-ball steering box, letting it turn smoothly while locating it against the axial loads fed back through the gear. It's part of the worm and valve assembly in the Adwest power-steering box.
Where does the race bearing sit in the steering box?
The race bearing supports the worm shaft within the Adwest steering box, at the worm and valve assembly. The worm drives the ball-nut and sector shaft, so a worn or rough race here usually shows up as steering slack or notchiness.
What are the signs the race bearing is worn?
A worn worm-shaft race usually causes play, notchy steering or a knock through the wheel on these power-steering boxes. It's renewed when the steering box is stripped and rebuilt, replacing the bearing in the worm and valve assembly.
Does this fit my vehicle, and which steering box?
This race bearing fits power-steering Adwest boxes on Land Rover Defender, Discovery 1 and Range Rover Classic. Discovery 1 fitment runs from FA393361 to WA799999, and the 2007-2016 Defender uses the fixed-ratio box from VIN 7A000001. Confirm your VIN before ordering.
