Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery (if working on drivetrain components).

2. Tire Inspection and Replacement

• Inspect Tires:
  • Check for uneven wear patterns, bulges, or punctures.
• Replace Tires (if necessary):
  1. Loosen the lug nuts using a socket wrench.
  2. Raise the vehicle using a jack and secure it with jack stands.
  3. Remove the wheel and inspect the tire.
  4. If replacement is necessary, install the new tire and torque the lug nuts to manufacturer specifications (typically around 80-100 ft-lbs for BMW).

3. Wheel Balancing

• Balance Tires:
  1. Mount the wheel on a wheel balancer.
  2. Spin the wheel to identify heavy spots.
  3. Attach weights as needed to achieve balance.

4. Wheel Alignment

• Adjust Alignment:
  1. Take the vehicle to an alignment rack.
  2. Adjust toe, camber, and caster angles according to manufacturer specifications.
  3. Test drive to ensure proper alignment.

5. Suspension Inspection and Repair

• Inspect Suspension:
  1. Visually check for worn bushings or damaged components.
  2. Replace any damaged parts (e.g., control arms, bushings).
  3. Torque all new parts to the manufacturer’s specifications.

6. Drivetrain Inspection

• Check Drivetrain Components:
  1. Inspect the driveshaft for any signs of wear or damage.
  2. Ensure CV joints are not torn or leaking grease.
  3. Replace any damaged components as necessary.
