Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gear, including gloves and goggles.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, tire iron, torque wrench.
Check and adjust tire pressures to match specifications (usually found on the driver's door jamb).
Inspect tires for damage; if any tire is damaged, replace it using the following steps:
1. Loosen lug nuts with a tire iron.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the damaged tire.
4. Install the new tire, hand-tighten the lug nuts.
5. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

3. Suspension Component Replacement

Tools Required: Socket set, torque wrench, pry bar, spring compressor (if needed).
If any suspension components are found damaged:
1. Raise and secure the vehicle.
2. Remove the wheel for access.
3. Detach the damaged component (e.g., strut or shock) from its mounting points using the socket set.
4. Install the new component and ensure it is properly aligned.
5. Reattach any other components and torque to specifications.

4. Wheel Alignment

Tools Required: Alignment machine (typically done by a professional).
After replacing tires and/or suspension components:
1. Take the vehicle to a professional alignment shop.
2. Ensure all alignment settings (camber, caster, toe) are adjusted to manufacturer specifications.
