Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is on a level surface and secure it with jack stands if elevating.

2. Drain and Replace Differential Fluid

Tools Required: Socket set, drain pan, funnel.
Remove the drain plug from the differential and allow the old fluid to completely drain into the pan.
Replace the drain plug and tighten it to the manufacturer's specifications.

3. Inspect and Replace Components

Tools Required: Wrench set, torque wrench, gasket scraper.
Remove the differential cover using a socket set.
Inspect gears, bearings, and seals for wear or damage.
If components are damaged, replace them appropriately. This may involve removing and replacing the ring and pinion gears or the entire differential assembly.

4. Reassemble and Refill

Clean the differential cover mating surface with a gasket scraper.
Apply a new gasket or sealant as necessary.
Reinstall the differential cover and torque the bolts to the manufacturer’s specifications.
Refilling: Use the proper type of differential fluid and fill it until it reaches the fill hole.

5. Final Checks

Reinstall any components removed during inspection or repair.
Perform a final torque check on all related bolts.
