To check the axleshaft bearing, raise the vehicle, remove the wheel and brake drum, and move the axle flange to check for wear. Look for differential lubricant leakage indicating a seal issue. To remove the axleshaft, drain the differential carrier, remove the lock bolt and shaft, and remove the C-lock. Carefully withdraw the axleshaft, avoiding oil seal damage. Reinstall in reverse order, using a new gasket and correct torque. Refill with correct lubricant. For a full-floating axleshaft, loosen lug nuts, raise the vehicle, remove the wheel and flange bolts, and pull out the axleshaft. Clean the flange, inspect and replace seals and bearings if needed. Install a new gasket, apply RTV sealant, and push the axleshaft into the housing. Install flange bolts and wheel, then lower the vehicle and tighten lug nuts.
