Land Rover Part Number: RTC4398 - Steering Box Sector Shaft
RTC4398 is a steering box sector shaft fitted in the steering box sector. The machined shaft converts rotary input from the steering column into the lateral movement of the sector gear and engages that gear to transfer force to the drag link or pitman arm on right hand drive Defender applications. Wear to the shaft or its mating surfaces (including the shaft diameter, keyways and the sector engagement face) can produce play in the steering or uneven steering effort; replacement restores the correct engagement geometry between the column input and the sector gear to maintain predictable steering response.
