Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Transmission Fluid

Remove the transmission dipstick and check the fluid level.
If the fluid is low or dirty, drain the transmission fluid using a fluid pump.
Replace with manufacturer-recommended transmission fluid.
Refill to the proper level and check for leaks.

3. Inspect Driveshaft and U-Joints

Raise the vehicle securely using jack stands.
Inspect the driveshaft for any visible cracks or signs of wear.
Check U-joints for play; replace if any movement is detected.
To replace U-joints, remove the retaining clips, pull the U-joint out, and install the new one, ensuring it is properly greased.

4. Examine Wheel Bearings and Brake Components

Remove the wheel and tire assembly.
Inspect the wheel bearings for any roughness or play; replace if necessary.
Check brake calipers and pads for wear; replace any worn components.
Reassemble the wheel assembly and torque lug nuts to the manufacturer’s specifications.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and take the vehicle for a test drive to verify that the grinding noise has been resolved.
