Drive Pinion Seal - Mopar (52070339AC)
Drive Pinion Seal – Mopar (52070339AC)
The Mopar Drive Pinion Seal (52070339AC) is a Genuine OEM drivetrain sealing component designed to prevent gear oil from leaking around the differential’s pinion shaft. Installed at the point where the driveshaft connects to the differential pinion, this seal helps retain lubricant inside the axle housing while protecting internal gears and bearings from contamination. Manufactured according to Mopar’s strict factory engineering standards, the drive pinion seal ensures reliable sealing performance and precise compatibility with the vehicle’s differential assembly.
Constructed from high-quality synthetic rubber with a reinforced metal outer casing, the seal is engineered to withstand continuous exposure to gear oil, rotational movement, and temperature fluctuations within the differential housing. The flexible sealing lip maintains consistent contact with the rotating pinion shaft, helping create a tight barrier that prevents oil leakage while keeping dirt, moisture, and debris out of the differential.
The 52070339AC drive pinion seal is engineered as a vehicle-specific direct-fit component, matching the original diameter, sealing lip design, and housing dimensions used in Mopar factory axle assemblies. Maintaining OEM specifications is essential for ensuring proper sealing and protecting the differential’s internal components. Aftermarket seals that do not meet factory tolerances may lead to leaks or premature wear.
For professional technicians, installing a Genuine Mopar drive pinion seal ensures that differential service procedures maintain manufacturer sealing standards and drivetrain reliability. For experienced DIY vehicle owners, selecting the OEM seal helps ensure correct installation and dependable sealing performance when servicing the differential.
A properly functioning drive pinion seal helps retain gear oil within the differential, maintain proper lubrication of gears and bearings, and prevent contaminants from entering the axle housing. Replacing a worn or leaking seal helps restore proper lubrication retention and supports long-term drivetrain durability.
• Genuine Mopar OEM drive pinion seal
• High-quality synthetic rubber sealing lip
• Reinforced metal outer casing for secure fitment
• Designed to retain differential gear oil
