Solution

1. Preparation

Gather tools: jack and jack stands, socket set, OBD-II scanner, and flashlight.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Inspect Transmission Fluid

Locate the transmission dipstick.
Remove the dipstick, wipe it clean, and reinsert it to check the fluid level.
If low, add the recommended transmission fluid type (check owner’s manual).
If the fluid is dark or has a burnt smell, consider a fluid change.

3. Check Driveshaft and CV Joints

Raise the vehicle using a jack and secure it with jack stands.
Inspect the driveshaft for any signs of wear, cracks, or damage.
Examine CV joints for any torn boots or excessive play; replace if necessary.

4. Inspect Wheel Bearings

Rotate each wheel by hand to listen for grinding noises.
Check for any play by rocking the wheel back and forth; replace if there is excessive movement.

5. Repair or Replace Parts

If the transmission fluid is low or burnt, perform a transmission fluid change.
Replace any damaged CV joints or driveshaft components as needed.
If wheel bearings are found to be faulty, replace them with new ones.
