Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use a jack to lift the vehicle and secure it with jack stands.

2. Inspect and Inflate Tires

Tools Required: Tire pressure gauge
- Check the tire pressure on all tires.
- Inflate or deflate each tire to the recommended PSI as indicated on the driver’s door jamb sticker.

3. Perform Wheel Alignment

Tools Required: Alignment rack or alignment tool
- Mount the vehicle on the alignment rack.
- Adjust toe, camber, and caster settings to manufacturer specifications.
- Ensure all alignment angles are within tolerance.

4. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, and possibly a spring compressor
- Visually inspect all suspension components for wear or damage.
- Replace any worn components (e.g., bushings, struts) using the socket set.
- Torque new components to manufacturer specifications.

5. Rotate Tires

Tools Required: Lug wrench, jack, jack stands
- Rotate the tires according to the recommended rotation pattern (e.g., front-to-back or crisscross).
- Ensure that lug nuts are torqued to manufacturer specifications after rotation.
