Solution

1. Preparation

Gather all necessary tools and parts before starting the repair.
Safely elevate the vehicle using a jack and secure with jack stands.

2. Inspect and Replace Worn Components

Inspect Shock Absorbers and Struts
- Check for oil leakage and physical integrity.
- If damaged, remove the bolts securing the shock absorbers and struts and replace with new units. Torque bolts to manufacturer specifications (typically around 40-50 ft-lbs).
Inspect Control Arms and Bushings
- Check control arms for bends or cracks.
- Remove the control arm by unbolting it from the frame and the wheel hub. Replace any worn bushings with new ones. Use a bushing removal tool for easier extraction.

3. Reassemble Components

Reinstall all components in reverse order of removal.
Ensure all bolts are torqued to specifications and check alignment if necessary.

4. Final Inspection

After reassembly, perform a final visual check to ensure all components are correctly installed.
Lower the vehicle and perform a bounce test to ensure the suspension is functioning properly.
