However, regardless of what is broken with the Hummer  suspension, you should not drive the vehicle. This is because, if your vehicle is experiencing a damaged or collapsed spring, this can cause sagging – which could cause more damage to your vehicle over time.

The main components of the suspensions system include the springs, shock absorbers, struts, control arms, and more. Being exposed on the bottom of your vehicle, these parts are constantly exposed to debris, rocks, speed bumps, potholes, and other driving occurrences which can potentially damage components.
