Per I-CAR curriculum: “Coil springs may need to be replaced in pairs if:

  • a match to the undamaged coil spring cannot be identified or obtained.
  • the undamaged coil spring appears to be aged or worn.
Struts and shock absorbers may need to be replaced in pairs if:
  • a match to the undamaged strut or shock cannot be identified or obtained.
  • the undamaged strut or shock appears to be aged or worn.

For example: a vehicle with very low mileage or a vehicle that has recently had the struts replaced as part of regular maintenance may only require the damaged strut be replaced.

Stabilizer links are replaceable as a single part and generally do not require being replaced in pairs.

Leaf springs may need to be replaced in pairs if:

  • a match to the undamaged leaf spring cannot be identified or obtained.
  • the undamaged leaf spring appears to be aged or worn."
