What It Helps Address

• Differential gear oil seepage at the pinion area
• Contamination from a worn or hardened seal lip
• Noise or driveline issues caused by low lubricant level
• Service replacement needs on listed heavy-duty axle applications

Installation Notes and Tips

Confirm axle configuration, ring gear size, and the listed 1st design or 10.5-inch ring gear notes before ordering. Clean the seal bore and pinion area thoroughly before installation, and inspect the pinion yoke and mating surfaces for wear that could affect sealing performance. Match the part number PT2286 to the vehicle listing to verify application coverage.

Quality Assurance

PT2286 is cataloged for broad heavy-duty axle coverage across Chevrolet and GMC applications. Use the listed fitment notes to confirm the correct design before installation.
