Carefully pry the cover off using a flat screwdriver, ensuring not to damage the mating surface.
Clean the mating surface on the differential housing with a scraper.

4. Inspect Internal Components

Examine the ring and pinion gears for wear or damage.
Inspect the differential bearings and carrier for excessive play or noise.
Rotate the pinion by hand; listen for grinding noises.

5. Replace Damaged Components

If any components are worn or damaged, replace them as necessary.
Use OEM parts for optimal performance and compatibility.
Reassemble the differential by reversing the removal steps.

6. Refill Differential Fluid

Replace the differential cover using a new gasket or sealant as required.
Tighten the cover bolts to the manufacturer’s specified torque value.
Refill the differential with the correct type and amount of fluid as per Honda specifications.
