- Visually inspect control arms, ball joints, tie rods, and bushings for wear or damage.
- Replace any worn or damaged components before proceeding with alignment.

4. Perform Wheel Alignment

Sub-steps:
- Attach alignment tools to the front wheels according to the manufacturer's instructions.
- Adjust camber and toe settings as per the specifications found in the vehicle service manual.
  - Camber: Adjust to within ±0.5 degrees of manufacturer specifications.
  - Toe: Set to within 1/16 inch (1.5 mm) of parallel.
- Tighten all adjustment bolts to specified torque values.
