Detailed Description
This SKF differential pinion seal is engineered for the rear differential pinion area, where the seal must retain gear oil while keeping road debris and moisture out. The 3.501-inch outside diameter, 1.875-inch shaft diameter, and 0.438-inch width provide the dimensional reference needed for correct application matching. SKF 18924 is listed for 1951-1952 Chrysler Imperial rear applications, making it a direct fitment reference for classic Chrysler Imperial rear axle service. This part cross-references 49658 and 1271105 for the same application.
What It Is Used For
- Stopping gear oil seepage at the differential pinion area
- Reducing contamination entry into the rear axle assembly
- Restoring sealing performance on worn or leaking pinion seals
- Supporting proper lubrication retention in the rear differential
Installation Notes and Tips
Verify shaft diameter, outside diameter, and width against the original seal before installation. Inspect the pinion yoke and sealing surface for wear, scoring, or corrosion, since surface damage can affect seal life. Clean the housing bore thoroughly and install the seal squarely to avoid distortion. Confirm rear axle fitment for 1951-1952 Chrysler Imperial before ordering.
