Solution

1. Preparation

Tools Required: Socket set, jack stands, torque wrench, pry bar, and a rubber mallet.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Worn Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to access the suspension components.
3. Inspect the struts and shocks for signs of leakage or physical damage.
4. Use a pry bar to check the sway bar links for play; replace if they are loose or damaged.
5. If the struts or shocks are worn, unbolt them from the lower control arm and upper mounts. Replace with new components and torque to manufacturer specifications (typically 30-50 ft-lbs for strut mount bolts).
6. Reinstall the wheels and lower the vehicle.

3. Tighten or Replace Loose Bolts

Sub-steps:
1. Inspect all mounting bolts on the suspension components and tighten as necessary.
2. If any bolts are stripped or damaged, replace them with new ones.
3. Use a torque wrench to ensure all bolts are tightened to the manufacturer's specifications.
