Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Drain Differential Fluid

Tools Required: Socket set, drain pan
Remove the differential cover bolts using a socket.
Carefully pry the differential cover off to avoid damaging the gasket.
Allow the old fluid to drain completely into the drain pan.

3. Inspect Internal Components

Tools Required: Flashlight, inspection mirror
Examine the gears and bearings inside the differential for signs of wear, damage, or metal shavings.
Check the condition of the ring and pinion gears, ensuring they are properly aligned.

4. Replace Components (if necessary)

If any components are damaged, replace them with OEM or high-quality aftermarket parts.
Install new bearings and seals as needed, ensuring to torque them to manufacturer specifications.

5. Reassemble Differential

Clean the mating surfaces of the differential cover and housing.
Apply a new gasket or sealant as per manufacturer recommendations.
Reattach the differential cover and tighten the bolts to the specified torque.

6. Fill with New Differential Fluid

Parts Required: Differential fluid (as specified in owner’s manual)
Pour new differential fluid into the fill hole until it reaches the recommended level.
Reinstall the fill plug, ensuring it is tight.
