Solution

1. Preparation

Tools Required: Safety glasses, gloves, jack stands, wrench set, socket set, and a torque wrench.
Safety Warnings: Ensure the vehicle is on a level surface and secured with jack stands before starting any work.

2. Addressing Fluid Issues

Sub-steps:
1. Transmission Fluid: If low, add the manufacturer-specified type of transmission fluid. Check for leaks.
2. Differential Fluid: If low or contaminated, drain the differential and replace with the recommended fluid. Ensure to also check the seals for leaks.

3. U-Joint Replacement (if worn)

Sub-steps:
1. Remove Driveshaft: Use a wrench to unbolt the driveshaft from the differential and transmission.
2. Inspect U-Joints: Check for play; if worn, replace them.
3. Install New U-Joints: Use a press to install new U-joints and reassemble the driveshaft.
4. Torque Specifications: Reinstall bolts to the manufacturer’s specified torque (consult service manual).

4. Wheel Bearing Replacement (if necessary)

Sub-steps:
1. Remove Wheel: Take off the wheel and tire assembly.
2. Remove Brake Components: Detach the brake caliper and rotor.
3. Inspect Bearing: Check the wheel bearing for roughness; if damaged, replace.
4. Install New Bearing: Press or tap in a new wheel bearing carefully.
5. Reassemble: Reinstall brake components and wheel, ensuring proper torque specifications.
