Before ordering, please confirm your differential part number or provide your full VIN for verification. Incorrect fitment caused by unverified OE references or vehicle configuration is the buyer’s responsibility. Installation Notes Ensure all old bearing races and oil seals are completely removed before installation. Clean the differential housing and all internal surfaces thoroughly to prevent debris contamination. Press bearings using the correct bearing press tools; do not hammer on the inner or outer race. Install oil seals evenly and flush with the housing; avoid tilting or over-driving the seals. Lubricate seal lips with gear-oil-safe grease before assembly to prevent dry running at first start. Set preload and backlash according to factory

specifications after assembly. Use GL-5 mechanical differential gear oil. Friction modifiers are not required for this bearing and seal kit. Check that the differential breather is open and not blocked to avoid pressure-related leaks. Torque all fasteners to OEM values using a calibrated torque wrench. After installation, perform a short test drive and check for abnormal noise or oil leakage. Recheck differential oil level after 50–100 km of driving.
