Frequently asked questions

What is the steering box sector shaft and what does it do?
The sector shaft is the output shaft of the recirculating-ball steering box. The worm and ball-nut drive its sector teeth, and the drop arm clamps to its splined lower end, passing steering movement into the track-rod linkage. This is the Adwest power-steering shaft.
Where does the sector shaft sit in the steering box?
The sector shaft runs vertically through the Adwest steering box, with its splined end protruding at the bottom for the drop arm. Inside, its teeth mesh with the ball-nut driven by the worm shaft, turning steering input into road-wheel movement.
Does this fit manual steering boxes?
No, this sector shaft is for power-steering Adwest boxes. It fits Land Rover Defender, Discovery 1 and Range Rover Classic with power steering. The 2007-2016 Defender application is the fixed-ratio Adwest box from VIN 7A000001.
How do I confirm this sector shaft fits my vehicle?
Check your steering box is the Adwest power-steering type and confirm your VIN against the fitment range. Discovery 1 fitment runs from FA393361 to WA799999, and Range Rover Classic splits in 1992 from VIN JA610294 for the power-steering version.
