Installation Notes and Tips
Verify the cup bore, length, and radius against the original race before installation. Press the taper bearing cup into a clean, properly prepared hub or axle seat to avoid distortion or misalignment. Inspect the matching bearing cone and related components for wear before reassembly. For Ford F-250 and Ford F-350 service, confirm the bearing and race dimensions match the original application exactly. Part number 563 should be installed only after the mating surfaces are cleaned and checked for damage.
