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 ? Serial # T03UG0037JXXXX
Axle Part#: 05038703XX ? Serial # T03UG0047HXXXX
