Ensure the vehicle is on a level surface, and engage the parking brake.
Disconnect the battery to prevent any electrical shorts during inspection.

2. Tire Inspection

Remove the front wheels using a jack and jack stands.
Inspect the tires for uneven wear or damage.
Replace tires if they show significant wear or damage.

3. Suspension Component Check

With the tires removed, inspect the control arms, bushings, and struts for signs of damage or excessive wear.
Replace any worn or damaged suspension components.

4. CV Joint and Axle Inspection

Inspect the CV joints for any torn boots or grease leakage.
Check for play in the axle joints by manually moving them up and down.
Replace any faulty CV joints or axles as necessary.
