Professional mechanic or wheel-end specialist installation recommended:

1. Ensure vehicle is safely raised - Use appropriate jack stands or a lift to support the axle
2. Remove the rear wheel - Remove the wheel and tire assembly to access the hub
3. Remove the brake drum or caliper - If equipped, remove the brake components to access the hub
4. Remove the hub assembly - Remove the axle shaft and hub nut; pull the hub assembly off the spindle
5. Remove the old oil seal - Carefully pry out the old seal from the hub or axle housing using a seal puller; avoid damaging the bore
6. Clean the housing bore - Thoroughly clean the seal bore and shaft surface; remove all old seal residue and debris
7. Inspect the shaft - Check the shaft surface for wear, scoring, or corrosion; replace if damaged
8. Lubricate the new seal - Apply clean gear oil or wheel bearing grease to the seal lip and outer case
9. Install the new seal - Press the new seal evenly into the housing bore using a proper seal driver; ensure it is fully seated
10. Check seal orientation - Ensure the seal lip faces the correct direction (toward the bearing/lubricant side)
11. Reinstall the hub assembly - Install the hub, bearings, and axle shaft; adjust bearing preload as specified
12. Reinstall brake components - Reinstall the brake drum or caliper and wheel
13. Check hub oil level - Top up hub oil or grease as required
14. Road test - Test drive to verify no leaks and smooth wheel operation
15. Check for leaks - Inspect the hub area for oil or grease seepage after driving
