Solution

1. Preparation

Gather required tools and parts.
Ensure vehicle is parked on a level surface and securely lifted using a jack and jack stands.
Disconnect the negative battery terminal for safety.

2. Inspect and Adjust Tire Pressure

Tools Required: Tire pressure gauge, air compressor
Check each tire's pressure and inflate or deflate as necessary to match the recommended specifications found in the owner's manual.

3. Tire Rotation and Inspection

Tools Required: Lug wrench, torque wrench
Remove the front left tire and inspect for uneven wear or damage.
Rotate tires (if applicable) to ensure even wear; follow a crisscross pattern.
Reinstall the tire, ensuring lug nuts are torqued to the manufacturer’s specifications (typically 100-120 ft-lbs).

4. Wheel Alignment

Tools Required: Alignment rack, camber/caster/toe gauges
Adjust the alignment settings according to manufacturer specifications:
- Toe: Typically should be between 0.05° to 0.15° (check exact specs).
- Camber: Should be within -0.5° to -1.5° (check exact specs).
- Caster: Ensure it’s balanced side-to-side.
Make necessary adjustments using the alignment equipment.

5. Suspension Inspection and Repair (if necessary)

Tools Required: Socket set, torque wrench, pry bar
Inspect control arms, tie rods, and bushings for signs of wear or damage.
Replace any worn components as needed, ensuring all new parts are torqued to specifications.
