LR043121 | Diff Lock Motor Housing - Rear Axle Electronic Lock | Range Rover & Discovery

Land Rover Part Number: LR043121 - Differential Locking Motor Housing

LR043121 is a Differential Locking Motor Housing fitted to the rear axle. The housing contains and mounts the electric motor that operates the electronic locking differential, positions the motor relative to the differential mechanism and protects the motor and its electrical connection from road debris and moisture. Where an electronic locking differential or torque-vectoring function is specified, this housing interfaces with the axle assembly and the vehicle electrical connector so the locking function can be driven by the vehicle control systems. The part is designed to match the mechanical and electrical interfaces used on the models listed below.
