The AEU2520 is a right-hand front drive shaft for Land Rover Defender models equipped with non-ABS axles, transferring drive from the differential to the front hub on the right-hand side of the vehicle. On axles coded 20L, 21L, 22L, and 23L, worn or damaged drive shafts commonly present as clicking under load, vibration through the steering, or visible grease loss from failed CV joints.
