Summary
Rear Axle Assembly If replacing Limited Spin Differential (LSD)/Anti-Spin Differential rear axles for any reason, the Mopar replacement axle will need the oil drained and re-filled with oil PN: 68083381AA (which contains updated friction modifier). This change was recently introduced in production to help address axle noise concerns being reported from the field while the vehicle is performing tight turning maneuvers. Failure to do so may result in a customer returning with noise complaints. NOTE: If the Mopar replacement axle serial number is past the following dates below for the corresponding axle part numbers, DO NOT DRAIN AND REFILL. The replacement axle will already have new fluid: Axle Part#: 53010668XX ? Serial # T03UG0047EXXXX Axle Part#: 53010669XX ? Serial # T03UG0047GXXXX Axle Part#: 68269917XX ?
