Installation Notes and Tips

Confirm the rear outer position, bearing type, and dimensions before installation. Clean and inspect the hub, spindle, and related sealing surfaces for wear, scoring, or contamination before pressing in the new bearing. Verify the application notes for axle-specific listings such as the Spicer 60-1 axle references on the Chevrolet C20 Suburban and K20 Suburban.

For best results, compare the removed bearing to WT18690 and confirm the 46 mm inside diameter and 17.5 mm width match the service requirement. Proper bearing preload and lubrication procedures should follow the vehicle manufacturer’s service information.
