Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and allow the vehicle to cool if it has been running.

2. Lift the Vehicle

Use a jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel, exposing the suspension components.

4. Inspect and Replace Components

Struts/Shocks:
- Check for oil leakage and physical damage.
- If defective, remove the strut assembly and replace with new struts or shocks, following the manufacturer’s specifications for installation.
Control Arms/Bushings:
- Examine for cracks or wear.
- If necessary, remove the control arm using a socket set and replace bushings or the entire control arm.
Ball Joints:
- Inspect for play and wear.
- If damaged, remove the ball joint and replace it according to the service manual.

5. Reassemble and Lower Vehicle

Reattach the wheel and tighten the lug nuts to the specified torque (typically 80 ft-lbs for most Toyota models).
Remove the jack stands and lower the vehicle to the ground.
