Solution

1. Preparation

Ensure the vehicle is on a level surface and securely lifted using jack stands.
Gather necessary tools and parts.

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Jack and jack stands
Tire pressure gauge

2. Tire Inspection and Adjustment

Remove the tires from the vehicle using a socket set.
Inspect each tire for signs of uneven wear, bulges, or punctures.
Check tire pressure and inflate to the manufacturer's recommended PSI.
If tires are damaged, replace them with new tires of the same specifications.
Reinstall the tires and torque the lug nuts to the manufacturer’s specifications.

3. Drivetrain Inspection

Visually inspect the drive shaft and CV joints for any signs of wear, cracks, or grease leakage.
If damaged, replace the affected components.
- For CV joint replacement, remove the axle assembly and install a new CV joint, ensuring proper lubrication.
Check the motor mounts for cracks or excessive wear.
- If needed, replace the motor mounts by unbolting them and installing new mounts, ensuring proper positioning and torque.

4. Suspension Component Check

Inspect the suspension components, including struts and shocks, for leaks or damage.
If any components are worn, replace them with new parts.
- When replacing struts, ensure to align the mounting bolts and torque them to specifications.
Check the wheel alignment and adjust if necessary.
