Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Use wheel chocks for added safety.

2. Inspect and Replace Wheel Bearings

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the hub assembly.
3. Inspect the wheel bearing for play by manually moving the hub; replace if necessary.
4. Use a bearing puller to remove the old bearing and press in a new one.
5. Reassemble the wheel and lower the vehicle.

3. Check and Change Differential Fluid

Sub-steps:
1. Locate the differential housing and remove the fill plug.
2. Check fluid level; if low, drain the old fluid using a drain pan.
3. Inspect for metal shavings in the fluid; if present, further inspection is needed.
4. Refill with manufacturer-recommended differential fluid using a pump.
5. Replace the fill plug and ensure it is secure.

4. Inspect Driveshaft and CV Joints

Sub-steps:
1. Raise the vehicle and secure with jack stands.
2. Visually inspect the driveshaft for any signs of damage or corrosion.
3. Check CV joints for torn boots or excessive play; replace if damaged.
4. Lubricate if applicable and reassemble.

5. Transmission Fluid Check

Sub-steps:
1. Start the engine and allow it to reach operating temperature.
2. With the engine running, check the transmission fluid level using the dipstick.
3. If the fluid is low, add manufacturer-recommended fluid until it reaches the proper level.
4. Inspect for leaks around the transmission pan and seals.
