- Raise the front of the vehicle using a jack and secure it on jack stands.
- Visually inspect the steering rack, tie rods, and other components for damage or wear.
- Check for any loose bolts or fittings and tighten them to manufacturer specifications.
Tools Required: Socket set, torque wrench.

4. Wheel Bearing Inspection

Sub-steps:
- Spin the wheel by hand and listen for any grinding noise.
- Check for excessive play by gripping the wheel at 12 and 6 o'clock and rocking it back and forth.
- If play is detected, the wheel bearing may need replacement.
Tools Required: Socket set, torque wrench.

5. Tire Check

Sub-steps:
- Inspect the tires for uneven wear patterns, low pressure, or damage.
- Rotate or replace tires if necessary to ensure even wear.
Tools Required: Tire pressure gauge, jack, lug wrench.
