Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Inspect and Adjust Tire Pressure

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires as needed to match the manufacturer’s specifications (usually found on the driver’s door jamb).

3. Wheel Alignment

Tools Required: Alignment rack, alignment tool.
Position the vehicle on an alignment rack.
Follow the manufacturer's specifications to make adjustments to the camber, caster, and toe settings as needed.
Tighten all adjustment bolts to the specified torque values.

4. Inspect and Replace Worn Suspension Components

Tools Required: Socket set, torque wrench, jack stands.
Perform a visual and physical inspection of all suspension components.
Replace any worn parts (e.g., control arms, bushings, struts) with OEM or quality aftermarket parts.
Reassemble and torque all components to manufacturer specifications.

5. Tire Rotation or Replacement

If tread wear is excessive, consider rotating the tires to promote even wear.
If necessary, replace tires that are worn beyond safe limits.
Ensure all tires are balanced properly after installation.
