Installation Notes and Tips

Verify axle type, seal dimensions, and housing bore before installation. Clean the sealing surface thoroughly and inspect the shaft for wear, grooves, or corrosion that could affect sealing performance. For vehicles such as the Ford Explorer, Ford Escape, and Lincoln MKX, confirm the exact axle configuration listed in the fitment data before service. The part number WS710429 should be matched to the application during ordering and installation.
