Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather safety gear (gloves, goggles).

2. Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires to meet OEM specifications (usually found on the door jamb).
Recheck pressure after adjustment to confirm accuracy.

3. Perform Wheel Alignment

Use an alignment machine to check alignment settings.
Adjust the camber, caster, and toe angles as per the manufacturer's specifications.
Confirm the alignment is within acceptable limits and recheck after adjustments.

4. Inspect and Replace Suspension Components

Raise the vehicle securely using a jack and jack stands.
Inspect shocks, struts, and bushings for signs of wear or damage.
Replace any worn components using OEM or high-quality aftermarket parts.
Follow manufacturer torque specifications for bolt installation.

5. Check and Repair Brake System

Inspect brake calipers for proper operation, looking for signs of sticking.
Clean and lubricate caliper slides if necessary.
Replace any malfunctioning brake components (e.g., calipers, pads).

6. Tire Rotation

Rotate the tires according to the recommended pattern (e.g., front-to-back, side-to-side).
Ensure proper torque specifications for lug nuts when reinstalling.
Monitor for any change in wear patterns post-rotation.
