1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate the tires to match the recommended pressure specified in the owner’s manual.
Inspect the tires for visible damage, replacing any that are excessively worn or damaged.

3. Suspension Inspection and Repair

Inspect Components:
- Visually inspect shocks and struts for leaks or damage.
- Check bushings for signs of wear or deterioration.
Replace Damaged Components:
- If any suspension components are found to be faulty, remove and replace them.
- Use a socket set to remove the bolts securing the struts or shocks.
Reassembly:
- Ensure all bolts are torqued to the specified values in the service manual.
- Reconnect any electrical connections if applicable.

4. Wheel Alignment

Take the vehicle to a professional alignment shop to perform a four-wheel alignment.
Follow the technician’s recommendations for adjusting camber, caster, and toe settings.
