Solution

1. Preparation

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

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires to the manufacturer-recommended PSI, typically found on the driver’s side door jamb.

3. Tire Inspection and Rotation

Remove the front tires using a socket set.
Inspect the tread depth and look for uneven wear patterns.
If uneven wear is detected, rotate the tires or replace them as necessary.

4. Wheel Alignment

Take the vehicle to a professional alignment shop or perform a DIY alignment using alignment tools.
Adjust the toe, camber, and caster settings according to manufacturer specifications.

5. Suspension Component Inspection and Replacement

Visually inspect control arms, tie rods, and bushings for signs of wear or damage.
Replace any worn or damaged components using the appropriate tools (e.g., socket set, wrenches).
Torque new components to manufacturer-specified values.
