Solution

1. Preparation

• Gather Tools: OBD-II scanner, jack and jack stands, torque wrench, wheel alignment machine, basic hand tools (sockets, wrenches).
• Safety Warning: Ensure the vehicle is on a flat surface and that the parking brake is engaged.

2. Tire Inspection and Replacement

• Inspect tires:
  • Check for uneven wear or damages.
  • Measure tire pressure and inflate to the recommended PSI.
• Replace tires (if necessary):
  • Remove the wheel using a socket wrench.
  • Install new tires and torque the lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).

3. Wheel Alignment

• Perform alignment:
  • Use a wheel alignment machine to adjust the angles of the wheels.
  • Adjust camber, caster, and toe settings to meet manufacturer specifications.

4. Drivetrain Inspection and Repairs

• Inspect driveshaft and CV joints:
  • Remove any undercarriage covers if applicable.
  • Check for play in the CV joints and driveshaft.
  • Replace any damaged components (e.g., CV joints) as necessary.

5. Engine and Transmission Mounts

• Inspect and replace mounts:
  • Check for cracks or deterioration on the mounts.
  • Remove the old mount using a socket wrench.
  • Install new mounts and torque to specifications.

6. Suspension Components
