1. Clean all parts except the friction plates in the brake disc pack by using cleaning solvent. Use compressed air to clear the passages in the planetary ring gear and brake housing.
NOTICE: wear face protection when using compresses air.
2. Inspect the bearing rollers for pitting, scoring, deformation, or other damage. Check the inner face and bearing cage for deformation, dents, and other damage.
Check the associated bearing cups for scratches, grooves, or cracks. Check the bearings for rough spots or binding by holding bearing and rotating. If the bearing binds or action is not smooth, replace the bearing.
3. Inspect the bearing cups for pitting, scoring, cracks, or other damage. Replace if any of these conditions are seen.
NOTE: if a bearing or bearing cup requires replacement, the associated part must also be replaced.
4. Check the planetary ring gear, planetary gears, and planetary carrier gear teeth for cracks, breaks, chipping, or other damage. Replace the part if any of these conditions are seen. Check the planetary carrier shaft splines for broken, cracked, or twisted condition. Replace if needed.
5. Check the wheel end shaft for cracked, broken, or twisted splines. Replace if any of these conditions are seen.
