Solution

1. Preparation

Gather tools including a jack, jack stands, torque wrench, and alignment tools.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Adjust Tire Pressure

Remove valve caps from each tire.
Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate each tire to the manufacturer's recommended pressure as stated on the driver’s side door jamb.

3. Perform Wheel Alignment

Use an alignment machine to check and adjust the toe, camber, and caster.
- Toe: Adjust to manufacturer's specifications.
- Camber: Adjust as needed to ensure proper tire contact.
- Caster: Confirm proper angles for steering stability.
Torque all bolts to the specified values using a torque wrench.

4. Inspect and Replace Worn Suspension Components

Visually inspect all suspension components for wear or damage.
If any components are found to be worn:
- Remove the affected component using appropriate tools.
- Replace with OEM or equivalent parts.
- Reassemble and torque fasteners to specified values.

5. Rotate or Replace Tires

If tires are excessively worn, rotate them to promote even wear, or replace them if necessary.
Ensure that the new tires are balanced properly after installation.
