Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if any electrical components are to be serviced.

2. Raise the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure with jack stands to ensure safety.

3. Inspect and Replace Components

A. Inspect Control Arms and Bushings

Remove any protective covers if necessary.
Check for cracks or excessive wear in bushings.
If damaged, remove the control arm by:
1. Removing the bolts that secure the control arm to the subframe using a socket set.
2. Detaching the ball joint from the steering knuckle using a ball joint separator.

B. Replace Struts (if necessary)

Remove the strut assembly by:
1. Detaching the upper strut mount from the vehicle body.
2. Removing the lower strut bolts from the steering knuckle.
3. Replacing with a new strut.
Reassemble by reversing the removal steps, tightening all bolts to the manufacturer's torque specifications.

4. Reassemble and Lower Vehicle

Reinstall any covers or shields removed during inspection.
Lower the vehicle using the hydraulic jack.

5. Wheel Alignment

After repairs, perform a wheel alignment to ensure proper handling and tire wear.
