Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Lift the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Worn Suspension Components

Inspect Struts and Shocks:
- Remove the wheel to access the strut assembly.
- Check for oil leaks or physical damage on the struts.
- If worn, replace with OEM or quality aftermarket struts.
- Torque the upper and lower mounting bolts to the manufacturer's specifications (typically around 80-100 ft-lbs).
Check Sway Bar Links:
- Inspect sway bar links for play or damage.
- Remove the links if necessary and replace them with new ones.
- Torque the sway bar link nuts to the manufacturer's specifications (usually around 40-50 ft-lbs).
Examine Control Arms:
- Inspect control arms for cracks or excessive wear.
- If damaged, remove the control arm by loosening the bolts and replace it with a new component.
- Ensure all mounting hardware is torqued to specification.

3. Reassemble and Lower the Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
Remove the jack stands and lower the vehicle completely.
