Land Rover Part Number: LR139391 - Rear Suspension Arm
LR139391 is a rear suspension arm that locates the rear knuckle and transfers suspension and braking loads between the wheel hub and vehicle body on New Defender 2020 (L663). It provides a structural link between the rear wheel hub assembly and the vehicle structure, controlling wheel position during suspension movement and resisting lateral and longitudinal forces generated during cornering, acceleration and braking; where the arm mounts to the vehicle, bearings or bushings normally allow controlled pivoting and are common service items. Replacement of a worn or damaged arm restores correct wheel location and load paths within the rear suspension system.
