Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and ensure it is secure with wheel chocks.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is secured before crawling underneath.

3. Inspect and Replace Worn Components

Struts/Shocks Replacement:
- Remove the wheel to access the strut assembly.
- Unbolt the strut from the lower control arm and the top mount.
- Replace with new strut/shock and reassemble.
Bushings Replacement:
- If bushings are worn, remove the control arm or component housing.
- Use a bushing press to install new bushings.
Control Arm Replacement:
- If the control arm is damaged, unbolt it from the frame and the wheel hub.
- Install the new control arm and ensure it is torqued to manufacturer specifications.

4. Reassemble and Lower Vehicle

Reattach wheels and lower the vehicle back to the ground.
Torque wheel lug nuts to specifications.
