Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is in "Park" or "Neutral" if automatic or manual, respectively.

2. Adjust Tire Pressures

Tools Required: Tire pressure gauge, air compressor
Sub-steps:
1. Remove valve caps from all tires.
2. Use the tire pressure gauge to check the pressure of each tire.
3. Inflate or deflate each tire to match the manufacturer's recommended pressure found in the owner’s manual or on the driver’s door jamb.

3. Inspect and Replace Tires (if necessary)

Tools Required: Jack, jack stands, tire iron
Sub-steps:
1. Lift the front of the vehicle using the jack and secure with jack stands.
2. Remove the front wheels using the tire iron.
3. Inspect tire tread for uneven wear; replace tires if wear is excessive.
4. Reinstall wheels and lower the vehicle.

4. Perform Wheel Alignment

Tools Required: Alignment machine or alignment tools
Sub-steps:
1. Take the vehicle to an alignment shop or use alignment tools if available.
2. Adjust camber, caster, and toe settings according to manufacturer specifications.
3. Ensure all adjustments are properly documented and confirmed.

5. Inspect Suspension Components

Tools Required: Socket set, pry bar
Sub-steps:
1. Visually inspect control arms, bushings, and struts for damage or wear.
2. Use a pry bar to check for play in suspension joints.
3. Replace any damaged components with OEM or quality aftermarket parts.
