- Lift the front of the vehicle using a jack and secure it on jack stands.
- Visually inspect control arms, ball joints, and struts for any signs of wear, cracks, or damage.
Replace Components (if necessary):
- Remove the wheel using a socket set.
- If control arms or ball joints are damaged, use a ball joint press to remove the old components and install the new ones.
- Reassemble the suspension, ensuring all bolts are torqued to the manufacturer specifications.

3. Examine and Replace CV Joints

Inspect CV Joints:
- Check the CV boots for tears or grease leaks.
- Wiggle the axle to check for excessive play in the CV joints.
Replace CV Joint (if necessary):
- Remove the axle nut using a breaker bar.
- Disconnect the CV joint from the wheel hub and pull the axle out of the transaxle.
- Install the new CV joint and axle assembly, ensuring proper alignment and torque specifications for the axle nut.

4. Steering Rack Inspection and Adjustment

Inspect Steering Rack:
- Check the steering rack for any play or damage.
- Ensure all mounting bolts are secure.
Adjust or Replace (if necessary):
- If the steering rack is worn, disconnect and remove it.
