Solution

1. Preparation

Gather necessary tools and parts for the repair.
Safety gear should be worn (gloves, safety glasses).
Ensure the vehicle is parked on a level surface and the emergency brake is engaged.

2. Adjust Tire Pressure

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

3. Inspect and Replace Tires (if necessary)

Remove the tires from the vehicle using a socket set.
Inspect for uneven wear; replace any tires that are excessively worn or damaged.
If replacing tires, ensure they are mounted and balanced properly before installation.

4. Wheel Alignment

Using an alignment machine, adjust the front and rear wheel alignment to the manufacturer’s specifications.
- Camber: Should be within the specified range.
- Toe: Adjust toe-in or toe-out as needed.
- Caster: Ensure correct caster angle for stability.

5. Suspension Component Replacement (if needed)

If any suspension components (like control arms, bushings, or tie rods) are found to be damaged during inspection, replace them.
- Remove damaged component using appropriate sockets and wrenches.
- Install new component and torque to factory specifications.
