Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and a flashlight.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electronic suspension components.

2. Inspect Suspension Components

Raise the vehicle using a jack and secure it with jack stands.
Inspect the struts and shocks for any signs of leakage or physical damage.
Check sway bar links by trying to move them with a pry bar; replace if there's excessive play.

3. Tighten Loose Components

Use a socket set to check and tighten all bolts associated with the strut assembly and control arms.
Verify that sway bar brackets and links are properly fastened.

4. Replace Worn Parts

If any components such as shocks, struts, or sway bar links are found to be defective, remove the faulty part:
1. Remove the wheel for better access.
2. Unscrew the bolts holding the strut/shock in place and remove.
3. Install the new component and torque bolts to manufacturer specifications.
Reassemble the suspension components and ensure all parts are secure.

5. Recheck Alignment

After completing repairs, ensure that the vehicle's alignment is checked and adjusted if necessary.
