Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Raise the rear of the vehicle using a jack and secure it with jack stands.

2. Drain and Replace Differential Fluid

Tools Required: Socket set, torque wrench, drain pan, new differential fluid.
Remove the differential drain plug using a socket wrench and allow the fluid to drain completely into a pan.
Inspect the fluid for metal shavings or debris, which indicates internal wear.
Reinstall the drain plug with the specified torque (usually around 30 ft-lbs for most models).
Fill the differential with new fluid using a pump until it reaches the fill level (check owner’s manual for specific fluid type and capacity).

3. Inspect and Replace Differential Components

Tools Required: Socket set, torque wrench, pry bar, new bearings/seals (if needed).
Remove the differential cover by loosening the bolts (use a torque wrench for reinstallation).
Inspect the gears, bearings, and spider gears for signs of wear or damage.
If any components are damaged, replace them with OEM parts.
Clean the mating surfaces of the differential cover and housing to ensure a proper seal.
Reinstall the differential cover with a new gasket or sealant, torquing bolts to manufacturer specifications.

4. Reassemble and Lower Vehicle

Recheck all connections and ensure there are no loose components.
Lower the vehicle from the jack stands and remove the jack.
