Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Suspension Components

Inspect Struts and Shocks:
- Remove the wheel to access the strut assembly.
- Check for any fluid leakage from the strut or shock absorber.
- If damaged, replace with OEM or high-quality aftermarket parts.
Replace Worn Bushings:
- Use a bushing removal tool to extract old bushings from control arms.
- Install new bushings, ensuring proper alignment and fitment.
Check Control Arms:
- Inspect control arms for cracks or bends. Replace if necessary.

3. Reassemble and Reattach Components

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).
Reconnect the battery.
