Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Wear safety glasses and gloves.

2. Check and Change Rear Differential Fluid

Locate the Differential: Identify the rear differential housing beneath the vehicle.
Check Fluid Level: Remove the fill plug and check if the fluid is at the correct level. Add fluid if necessary.
Drain Old Fluid: Remove the drain plug and allow old fluid to completely drain into a container.
Replace with New Fluid: Use the manufacturer-recommended rear differential fluid (e.g., Honda Dual Pump Fluid or equivalent) and fill to the correct level.
Reinstall Plugs: Replace the drain and fill plugs and torque them to the manufacturer's specifications.

3. Inspect Rear Axle Bearings

Remove Wheels: Use a lug wrench to remove the rear wheels.
Inspect Bearings: Check for any signs of play or roughness by rotating the hub.
Replace Bearings if Necessary: If bearings are worn, remove the hub and replace them with new ones, following proper removal and installation procedures.

4. Inspect Driveshaft

Visual Inspection: Look for any visible damage or excessive rust on the driveshaft.
Check U-Joints: Grasp the driveshaft and check for any excessive movement in the U-joints.
Replace if Worn: If U-joints are found to be worn, they should be replaced.

5. Check Tires

Tread Inspection: Examine the tire tread for uneven wear patterns or cupping.
Rotate Tires: If uneven wear is found, rotate the tires and check alignment.
