1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and securely raise it using jack stands.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Differential Fluid

Tools Required: Socket set, fluid pump, torque wrench.
Remove the differential cover bolts using a socket and ratchet.
Allow any residual fluid to drain into a suitable container.
Inspect the condition of the fluid; if it's metal-laden or burnt, it may indicate internal damage.
Clean the differential cover and replace the gasket if necessary.
Refill with the manufacturer-recommended differential fluid using a fluid pump.
Torque the cover bolts to the manufacturer’s specifications.

3. Check and Replace Rear Wheel Bearings

Tools Required: Bearing puller, socket set, torque wrench.
Remove the rear wheels and inspect the brake drum or rotor for damage.
Using a bearing puller, remove the wheel bearings if they are found to be worn or damaged.
Replace with new bearings, ensuring they are properly lubricated.
Reassemble the brake components and wheel, and torque to specifications.

4. Inspect and Repair Suspension Components

Tools Required: Socket set, torque wrench, pry bar.
Inspect all suspension components including control arms, bushings, and shocks for wear.
Replace any worn or damaged parts.
Tighten all suspension bolts to the manufacturer's torque specifications.
