Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, wrench set, torque wrench, OBD-II scanner.
Safety Warnings: Ensure the vehicle is securely raised and supported before working underneath. Disconnect the battery if necessary.

2. Replace Rear Axle Bearings

Remove the Rear Wheel: Use a socket set to remove the lug nuts and take off the rear wheel.
Remove Brake Components: Remove the brake caliper and rotor to access the axle assembly. Secure the caliper with a bungee cord or similar to avoid strain on the brake line.
Disconnect the Axle Shaft: Remove the axle nut using a socket set, then detach the axle shaft from the differential.
Extract the Old Bearings: Use a bearing puller to remove the old axle bearings from the axle housing.
Install New Bearings: Lubricate the new bearings and press them into place using a bearing installer. Ensure they are seated properly.
Reassemble the Axle: Reverse the disassembly steps to reattach the axle shaft, brake components, and wheel. Torque all fasteners to the manufacturer’s specifications.

3. Inspect and Replace Differential Fluid

Drain Differential Fluid: Remove the drain plug from the differential housing and allow the fluid to completely drain into a container.
Inspect for Metal Shavings: Check the drained fluid for metal particles or debris that could indicate internal damage.
Replace with New Fluid: Reinstall the drain plug, then refill the differential with the manufacturer-recommended gear oil through the fill hole until it reaches the proper level.
