Installation Notes and Tips

Confirm axle position and seal dimensions before installation. Inspect the pinion yoke or shaft sealing surface for grooves, corrosion, or wear that could affect sealing performance. Clean the housing bore thoroughly and install the seal squarely to avoid distortion. Verify the pinion bearing preload and differential condition during service, especially on high-mileage Mitsubishi Montero and Dodge Ram 50 rear axle repairs.
