How do you know when a vehicle needs new springs PDF Print E-mail
Information - FAQ

When the original springs are no longer able to maintain proper ride height or are not capable of handling vehicle load requirements, new springs are in order.

All springs sag with age. The constant load they bear leads to creep within the molecular structure of the metal. Over time, the spring weakens and begins to lose height (coil spring) or arch (leaf spring).

As the spring settles, ride height decreases and causes undesirable changes in wheel alignment. That is why alignment technicians are always supposed to measure ride height before they realign the wheels. More than an inch of sag usually means time for new springs.
