Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure in all tires.
Inflate or deflate tires as needed to match the manufacturer's recommended pressure, usually found on the driver’s door jamb.
Recheck tire pressure after adjustments.

3. Tire Inspection and Rotation

Remove the wheel lug nuts using a lug wrench.
Inspect the front tires for uneven wear; replace if necessary.
If uneven wear is noted, rotate the tires according to the manufacturer’s guidelines.
Reinstall lug nuts and torque them to the manufacturer's specifications (typically 80-100 ft-lbs).

4. Wheel Alignment Adjustment

Use an alignment machine or take the vehicle to a professional for a four-wheel alignment.
Adjust toe and camber settings according to manufacturer specifications.
Test drive the vehicle post-alignment to check for improvement.

5. Suspension Component Inspection and Replacement

Raise the vehicle using a jack and secure with jack stands.
Inspect ball joints, tie rods, and control arms for play or damage.
Replace any worn components using a socket set and torque to specifications.

6. Brake System Inspection

Remove the wheel and inspect the brake caliper for sticking or dragging.
Ensure that the brake pads and rotors are in good condition; replace if necessary.
Reinstall the wheel and repeat the torque procedure for lug nuts.
