Use a jack to lift the front end of the vehicle and secure it with jack stands.
Tools Required: Floor jack, jack stands.

3. Inspect Suspension Components

Remove the front wheels using a socket set.
Visually inspect the control arms, ball joints, and bushings for wear or damage.
If any components are damaged, proceed to replace them.
Torque specifications for wheel lug nuts: 100 Nm (74 lb-ft).

4. Check CV Joints

Inspect the outer and inner CV joints for any cracks in the rubber boot.
If damaged, replace the CV axle assembly.
Tools Required: CV joint puller, socket set, torque wrench.

5. Replace Strut Mounts (if necessary)

Remove the strut assembly from the vehicle by taking off the nuts securing it to the upper mount.
Inspect the strut mount for wear and replace if damaged.
Reassemble the strut, ensuring all nuts are torqued to specifications (typically 20 Nm or 15 lb-ft).
