Solution

1. Preparation

Gather Tools: OBD-II scanner, socket set, torque wrench, jack stands, and a fluid pump.
Safety Warning: Ensure the vehicle is on a level surface, and use wheel chocks to prevent rolling.

2. Fluid Inspection

Check Rear Differential Fluid:
1. Remove the fill plug on the rear differential.
2. Inspect the fluid for contamination or metallic particles.
3. If the fluid is low or dirty, drain the old fluid using a fluid pump.

3. Replace Differential Fluid

Replace with New Fluid:
1. Refill the differential with manufacturer-recommended fluid (e.g., 75W-140 synthetic gear oil).
2. Torque the fill plug to the manufacturer specifications (usually around 30 ft-lbs).

4. Inspect and Replace Bearings

Check Rear Axle Bearings:
1. Remove the rear wheels and drums or rotors.
2. Inspect axle bearings for any signs of wear or damage.
3. If damaged, replace the bearings using a bearing puller.

5. Inspect Universal Joints

Check U-Joints:
1. Inspect the universal joints for any play or excessive wear.
2. Replace any worn U-joints by removing the driveshaft and using a press to install new joints.

6. Suspension Inspection

Inspect Suspension Components:
1. Check control arm bushings, shock absorbers, and springs for damage.
2. Replace any worn or damaged components as necessary.
