ATP can be hydrolyzed in two ways: the removal of terminal phosphate to form adenosine diphosphate (ADP) and inorganic phosphate, or the removal of a terminal diphosphate to yield adenosine monophosphate (AMP) and pyrophosphate.
Driving with failing or broken struts is dangerous because they do not sufficiently dampen side-to-side and front-to-back weight transfers.
Common signs that you need to replace your shocks and struts are: extended braking distance, your vehicle bounces after driving over speed bumps or driveway ramps, unstable steering and reduced tire grip and stability. If it's time to replace your shocks and struts, consider your vehicle and your driving conditions.
