Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely jack it up.
Use jack stands for safety.

2. Remove Damaged Components

Control Arms:
- Remove the wheel using a socket set.
- Unbolt the control arm from the chassis and the wheel hub using the appropriate socket size.
- Carefully remove the control arm from the vehicle.
Sway Bar Links:
- Locate the sway bar links and remove the nuts securing them to the sway bar and lower control arm using a wrench.
- Pull the sway bar link out of its mounts.

3. Inspect and Replace Components

Inspect bushings for cracks or wear; replace if necessary.
Check struts for signs of leaking oil; replace if leaking.
Install new components (control arms, sway bar links) by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications.

4. Reassemble and Lower the Vehicle

Reattach the wheel and tighten lug nuts in a crisscross pattern to ensure even pressure.
Lower the vehicle from the jack stands and perform a final torque check on all components.
