Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace CV Joints

Lift the Vehicle: Use a jack to lift the front of the vehicle and secure with jack stands.
Remove Wheel: Use a socket set to remove the wheel on the affected side.
Examine CV Joint: Look for any tears in the CV boot or grease leakage.
Replace CV Joint:
- Remove the axle nut using a breaker bar.
- Separate the CV joint from the hub using a CV joint puller or hammer carefully.
- Install the new CV joint by reversing the removal process and torque the axle nut to manufacturer specifications (typically around 250 Nm).
- Reinstall the wheel and lower the vehicle.

3. Inspect and Replace Axle Shaft (if necessary)

Check Axle Shaft Alignment: If the CV joint is fine, verify the axle shaft’s alignment.
Remove and Replace:
- Remove the axle shaft from the transmission if misalignment is found.
- Replace with a new axle shaft and ensure proper alignment and secure it.
- Torque the bolts to manufacturer specifications.

4. Inspect Engine and Transmission Mounts

Visual Inspection: Check for cracks or signs of wear on engine and transmission mounts.
Replace Mounts (if damaged):
- Remove the fasteners securing the mount using a socket set.
- Replace with new mounts and torque to specifications.

5. Reassemble and Test

Reinstall all components removed during the process.
Reconnect the battery and start the vehicle.
