Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and safely elevated with jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Worn Components

Inspect Struts/Shocks:
- Remove the wheel to access the suspension components.
- Check for leaks or damage on the struts/shocks. If damaged, proceed to replace them.
Replace Struts (if necessary):
- Tools Required: Socket set, torque wrench, spring compressor.
- Remove the bolts securing the struts to the control arm and the strut tower.
- Use a spring compressor to safely compress the spring before removing the strut assembly from the vehicle.
- Install the new strut assembly, ensuring all bolts are torqued to the manufacturer's specifications.

3. Replace Bushings or Control Arms

Inspect Bushings:
- Check all rubber bushings for cracks or deterioration. Replace if necessary.
Replace Control Arm (if necessary):
- Tools Required: Socket set, pry bar, torque wrench.
- Remove the bolts securing the control arm to the frame and the steering knuckle.
- Install the new control arm and torque bolts to specifications.

4. Reassemble and Lower Vehicle

Reattach the wheel and lower the vehicle to the ground.
Reconnect the negative battery terminal.
