2. Remove and Inspect Components

Sway Bar Links:
- Use a socket set to remove the bolts securing the sway bar links.
- Inspect for wear or looseness; replace if damaged.
Control Arms:
- Remove the bolts securing the control arms using a torque wrench to ensure proper reassembly.
- Check bushings and ball joints for play; replace if excessive wear is found.
Shock Absorbers:
- Detach the upper and lower bolts holding the shock absorbers in place.
- Remove the shocks and inspect for leaks; replace if necessary.
