Solution

1. Preparation

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

2. Tire Inspection and Replacement

Tools Required: Tire iron, jack, jack stands.
Sub-steps:
1. Loosen the lug nuts on the affected wheel before lifting the vehicle.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the wheel and inspect for damage such as bulges or punctures.
4. If tire damage is found, replace with a new tire, ensuring it matches specifications (size, load rating).
5. Reinstall the wheel, hand-tighten lug nuts, lower the vehicle, and then torque to manufacturer specifications (typically around 76 ft-lbs for many RAV4 models).

3. Suspension Component Replacement

Tools Required: Wrench set, socket set, torque wrench.
Sub-steps:
1. Remove the wheel to access suspension components.
2. Inspect struts and shocks for leaks or damage; if damaged, remove the old component by unbolting it from the top mount and lower control arm.
3. Install the new strut or shock, ensuring all fasteners are torqued to specification.
4. Reattach any sway bar links if they were disconnected.

4. Wheel Alignment

Tools Required: Alignment machine.
Sub-steps:
1. After replacing tires and suspension components, take the vehicle to a professional alignment shop.
2. Follow the alignment procedure, ensuring that all angles (camber, caster, toe) are set to manufacturer specifications.
3. Record the alignment settings for future reference.
