NISSAN M9062-0020P Differential Oil Seal

The genuine NISSAN M9062-0020P differential oil seal is an essential drivetrain sealing component. Its primary function is to securely retain gear oil inside the differential along the rotating shafts while preventing external dirt, dust, and moisture from entering the housing, averting premature wear of internal gears and bearings.

Operating Description and Symptoms of Failure

The oil seal forms a dynamic seal between the rotating shaft and the stationary differential housing. Over mileage, continuous mechanical friction and thermal stress can cause the elastomer lip material to age, harden, or wear over time.

Common symptoms of seal wear include:

• Oil film or intensive oil leakage on the differential housing or around the output shaft area
• Oil drops under the vehicle during prolonged parking
• Drop in gear oil level, which can lead to insufficient lubrication and increased drivetrain noise (whining or humming)
