Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Transmission Fluid

Tools Required: Socket set, funnel, fluid pump.
Remove the transmission fluid drain plug and let the old fluid drain into a suitable container.
Inspect the old fluid for metal shavings or debris. If present, further inspection of the transmission may be required.
Replace with manufacturer-recommended transmission fluid, using a fluid pump to refill through the fill hole.
Reinstall the drain plug and torque to manufacturer specifications.

3. Inspect and Repair Driveshaft and Axles

Tools Required: Jack and jack stands, socket set, torque wrench.
Raise the vehicle and secure it on jack stands.
Visually inspect the driveshaft and axles for any signs of damage or wear (e.g., cracks or torn boots).
If damage is found, remove the affected component using a socket set and replace it with new parts, ensuring proper alignment and torque specifications are followed.

4. Check and Refill Rear Differential Fluid

Tools Required: Socket set, differential fluid, sealant.
Locate the rear differential and remove the fill plug.
Check the fluid level and condition; replace if necessary.
If fluid is low, refill using manufacturer-recommended differential fluid.
Reinstall the fill plug and torque to specifications.

5. Inspect Suspension Components

Tools Required: Socket set, pry bar, torque wrench.
Inspect suspension components for wear or damage, particularly rubber bushings and struts.
Replace any damaged components, ensuring to torque all bolts to specification during reinstallation.
