Tools Required: Jack and jack stands, socket set, torque wrench
Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect control arms, ball joints, and bushings for any signs of wear or damage.
Use a torque wrench to check the tightness of all suspension bolts as per manufacturer specifications.

3. Check Brake Components

Remove the front wheel using a socket set.
Inspect the brake pads for uneven wear; replace if necessary.
Check brake rotors for scoring or warping; resurface or replace as needed.

4. Examine Power Steering System

Check the power steering fluid reservoir for proper fluid level; top off with manufacturer-recommended fluid if low.
Inspect the power steering pump for leaks or unusual noise when turning the wheel.
