Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely lifted with jack stands.
Safety glasses and gloves should be worn during the repair.

2. Remove Wheel

Use a socket set to loosen and remove the lug nuts.
Carefully take off the wheel to access the suspension components.

3. Inspect and Replace Components

Struts/Shocks:
- Check for visible leaks or dents.
- If faulty, remove the strut assembly using a socket set to unbolt it from the strut tower and lower control arm.
- Replace with new struts/shocks, ensuring to torque bolts to manufacturer specifications.
Bushings:
- Inspect rubber bushings for cracks or wear.
- If damaged, remove the old bushing using a bushing removal tool.
- Install new bushings, ensuring proper alignment and seating.
Ball Joints:
- Check for play by moving the joint; if it feels loose, it may need replacement.
- Remove the ball joint from the control arm using a ball joint separator.
- Install a new ball joint, ensuring it is secured tightly.

4. Reassemble Components

Reattach the strut assembly and secure it with bolts.
Reinstall the wheel and hand-tighten the lug nuts initially.

5. Final Checks

Lower the vehicle and torque the lug nuts in a criss-cross pattern to the specified torque value.
Conduct a test bounce to ensure the suspension is functioning properly.
