Solution

1. Preparation

Gather necessary tools and parts before starting.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect and Replace Drivetrain Components

Visual Inspection
- Check for any visible damage on driveshafts, CV joints, and wheel bearings.
Fluid Check
- Remove the fill plug on the transmission and differential. Check for fluid level and condition; replace if contaminated or low.
Wheel Bearing & CV Joint Inspection
- Raise the vehicle, secure it with jack stands, and spin the wheels manually. Listen for grinding or roughness.
- If any components are damaged, replace them as follows:
  - CV Joint Replacement
    1. Remove the wheel and brake assembly.
    2. Detach the axle nut and slide the CV joint out of the transmission.
    3. Install the new CV joint, ensuring proper seating and torque the axle nut to manufacturer specifications.
  - Wheel Bearing Replacement
    1. Remove the wheel and brake assembly.
    2. Use a bearing puller to extract the old bearing.
    3. Press in the new bearing, ensuring it is seated correctly. Reassemble the wheel assembly.

3. Transmission Repair (if necessary)

If a transmission issue is detected, consider:
- Fluid Change
  - Drain the old fluid and replace it with manufacturer-recommended transmission fluid.
- Filter Replacement
  - Remove the transmission pan, replace the filter, and reassemble with a new gasket.
- Internal Inspection
  - If grinding persists, further disassembly may be needed for internal inspection and repairs.
