Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, OBD-II scanner.
Park the vehicle on a level surface and engage the parking brake. Use wheel chocks for safety.
Disconnect the battery to prevent electrical shorts during diagnostics.

2. Inspect and Replace Transmission Fluid

Check the transmission fluid level using the dipstick.
If low, add the recommended type of transmission fluid (consult the owner's manual for specifications).
If the fluid is dirty or burnt, perform a transmission fluid change.
- Sub-steps:
  1. Remove the transmission drain plug and let the fluid drain into a container.
  2. Replace the filter and gasket.
  3. Reinstall the drain plug and refill with new transmission fluid.

3. Inspect Driveshaft and CV Joints

Safely lift the vehicle and support with jack stands.
Visually inspect the driveshaft for any signs of wear, such as cracks or excessive rust.
Check CV joints for any tears in the boot or signs of grease leakage.
- Sub-steps:
  1. If damaged, remove the driveshaft or CV joint using a socket set.
  2. Replace with new components and torque to manufacturer specifications.

4. Inspect Wheel Bearings

Lift the front or rear of the vehicle and check for play in the wheel bearings.
- Sub-steps:
  1. Spin the wheel and listen for grinding noises.
  2. If noise is present, remove the wheel and hub assembly.
  3. Replace the bearings if worn and reassemble using a torque wrench to ensure correct tightness.
