Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Tire Inspection and Replacement

Sub-steps:
1. Inspect tire pressure using a tire pressure gauge and inflate to manufacturer specifications if necessary.
2. Check tread depth using a tread depth gauge; replace tires if tread is worn beyond legal limits (1/16 inch).
3. If tire replacement is needed, remove the wheel using a lug wrench and socket set.
4. Install new tires and torque the lug nuts to the manufacturer's specifications (usually 76-81 ft-lbs for RAV4).

3. Suspension Component Replacement

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Disconnect any necessary components, such as sway bar links, if replacing struts or shocks.
4. Use a socket set to remove the bolts securing the strut or shock absorber.
5. Replace with new struts or shocks, ensuring they match OEM specifications.
6. Reassemble all disconnected components and torque to specifications.
7. Reinstall the wheel and lower the vehicle.

4. Bushing and Mount Inspection

Sub-steps:
1. Inspect suspension bushings for cracks or deterioration; replace if necessary.
2. Use a bushing removal tool for easy replacement.
3. Ensure all bolts are tightened to manufacturer specifications.
