Differential Seal – Mopar (4736843AA)

Differential Seal is the sealing element between two surfaces that are bolted together. Surface finish on both faces matters as much as the seal itself, because a grooved flange will leak with any gasket.

Replace the Differential Seal whenever the assembly is opened, and always when the old seal shows a flattened profile or heat cracking. A seal that has taken a set will not re-seal at the same torque.

Reference number for the Differential Seal: 4736843AA. It is filed under Seals & O-Rings, and it is the number that has to match the part coming off the vehicle.

Genuine MOPAR supplied for this Differential Seal, with the engineering number unchanged from the factory reference stamped on the original.
