Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and safely secured with jack stands.
Disconnect the battery to prevent electrical shocks.

2. Drain Differential Fluid

Remove the differential cover bolts using a socket set.
Carefully pry off the differential cover.
Allow the old fluid to drain completely into a suitable container.
Inspect the magnet on the cover for metal shavings, indicating wear.

3. Inspect Components

Check the differential gears and bearings for signs of wear or damage.
Inspect the ring and pinion gears for scoring or chips.
Examine the differential case for cracks or excessive wear.

4. Replace Worn Parts

If any components are damaged, replace them with new parts. Ensure to use OEM or high-quality aftermarket parts.
If the bearings are worn, they should be replaced; use a bearing puller for removal.

5. Reassemble and Refill

Clean the differential cover and mating surface thoroughly.
Apply a new gasket or sealant to the differential cover.
Reinstall the cover and tighten the bolts to the manufacturer’s specified torque.
Refill with new differential fluid as specified in the owner’s manual (typically a high-quality gear oil).
