Land Rover Part Number: STC4403 - Rear Salisbury Differential Flange Kit
STC4403 is a Rear Salisbury Differential Flange Kit used to renew the rear output flange on Salisbury-type rear axles. The kit includes the flange, oil seal, nut and washer. The flange transfers torque from the differential output shaft to the propeller shaft flange while the oil seal prevents lubricating oil from escaping past the flange face; the nut and washer secure the flange against rotational load and resist loosening from vibration. Worn flange faces, a degraded oil seal or a loose securing nut can cause driveline vibration, noise or external oil leakage at the rear axle, so replacing the complete flange kit restores the mechanical joint and the oil seal. This kit is intended for Defender 110 and 130 wheelbase models fitted with a Salisbury rear axle and should be installed using standard axle flange torque and assembly practices. Use the compatibility data below to confirm fitment against your V.I.N.

- Defender (1987-2006) - Rear axle case assembly, 110 and 130 wheelbase, with Salisbury axle - From VIN XA159807
