Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Safety warning: Disconnect the battery if working on electronic components.

2. Adjust Tire Pressure

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires as necessary to match the recommended pressure listed in the owner’s manual.

3. Wheel Alignment

Lift the vehicle using a hydraulic jack and secure it on jack stands.
Remove the front wheels using a socket set.
Adjust the alignment settings (toe, camber, caster) according to manufacturer specifications using an alignment machine.
- Toe: typically 0.05 to 0.15 degrees.
- Camber: typically -0.5 to -1.5 degrees.
Reinstall the wheels and lower the vehicle.

4. Suspension Inspection and Repair

Visually inspect all suspension components for signs of wear or damage.
Replace any worn or damaged parts (e.g. control arms, bushings, tie rods).
Re-torque suspension components to manufacturer specifications.

5. Brake System Check

Inspect brake calipers for proper function and free movement.
Replace calipers if they are found to be sticking or damaged.
Ensure that brake pads are evenly worn and replace them if necessary.
