Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with jack stands.
Disconnect the battery to prevent accidental electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts before raising the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the front wheel.

3. Inspect and Replace Components

A. Control Arm Bushings

Tools Required: Socket set, torque wrench
Remove the bolts securing the control arms to the chassis and the subframe.
Replace worn bushings with new ones.
Reinstall and torque bolts to manufacturer specifications (usually around 80 Nm).

B. Ball Joints

Tools Required: Ball joint separator tool, socket set
Disconnect the ball joint from the control arm using a ball joint separator.
Replace with a new ball joint and secure it with the appropriate hardware.
Torque the ball joint nut to specifications (typically around 50 Nm).

C. Struts/Shocks

Tools Required: Strut spring compressor, socket set
Remove the strut assembly from the vehicle.
Use a spring compressor to safely release the tension on the coil spring.
Replace the strut insert or the entire strut assembly if damaged.
Reassemble the strut, ensuring all parts are tightened to specifications.

4. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and then torque the lug nuts to specifications (usually around 120 Nm).
Reconnect the battery.
