Product Line Details

Centric Premium Axle Shaft, Hub & Wheel Seals are part of Centric’s sealing lineup for driveline and wheel-end service. This product line focuses on maintaining lubricant retention and separation at critical rotating components, which is important when servicing rear axle assemblies on vehicles such as the Dodge Caravan and Plymouth Voyager.

Detailed Description

Centric 417.63001 is a drive axle shaft seal intended for rear inner applications on select Chrysler minivans. The seal’s dimensions are important for proper seating and sealing performance: 1.809-inch inside diameter, 2.361-inch outside diameter, and 0.371-inch width. When replacing a worn axle seal, matching these measurements helps restore the sealing surface and reduce fluid loss at the axle end.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues Addressed

• Gear oil or lubricant seepage at the rear axle shaft
• Contamination entering the axle bearing or seal area
• Wet residue around the rear inner axle seal
• Noise or wear related to low lubricant retention
• Service replacement for aged or hardened axle seals

Installation Notes and Tips

Verify the seal dimensions against the original part before installation. Inspect the axle shaft, hub surface, and seal bore for wear, scoring, or corrosion, since damaged surfaces can affect sealing performance. Clean the sealing area thoroughly and install the seal squarely to avoid distortion. Confirm vehicle application by year, make, model, and rear inner position before ordering.
