Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Wear safety gloves and goggles.

2. Check Tire Pressure

Use a tire pressure gauge to measure the pressure in all tires.
Inflate or deflate tires to the manufacturer's recommended pressure found on the door jamb sticker.

3. Wheel Alignment

Measure alignment angles (camber, caster, toe) using an alignment rack or DIY alignment tool.
Adjust alignment according to manufacturer specifications, typically:
- Camber: -0.5° to +0.5°
- Caster: +2° to +6°
- Toe: 0° to 1/16" toe-in

4. Inspect and Replace Suspension Components

Visually inspect all suspension components for wear.
Replace any worn or damaged parts, such as:
- Control arms
- Ball joints
- Struts or shocks
Follow the manufacturer's torque specifications for reassembly.

5. Tire Rotation

Rotate tires according to the recommended pattern (e.g., front to back, side to side).
Ensure lug nuts are torqued to the manufacturer's specifications (typically 80-100 ft-lbs).
