Replace with new shock absorbers, ensuring proper alignment of the mounting holes.
Torque bolts to manufacturer specifications (check service manual for specific torque values).

B. Sway Bar Links

Inspect sway bar links for damage or looseness.
If damaged, unbolt the sway bar link from the sway bar and control arm using a wrench.
Replace with new sway bar links and tighten to the specified torque.
