A clunk or knock every time you go over a pothole or speed bump is one of the more common suspension complaints, and usually traces back to a specific worn component rather than a mystery.
Usual Suspects
- Worn or torn sway bar end links
- Cracked or deteriorated suspension bushings
- A loose or worn strut mount
- Worn control arm bushings
- Loose or worn shock/strut hardware
Why It Happens on Bumps Specifically
Suspension components are designed to move and absorb impact. When a bushing, link, or mount wears out, it develops play — extra movement it shouldn't have. That play stays quiet on smooth pavement but announces itself as a clunk the moment the suspension compresses and rebounds over a bump.
Long Island Roads Don't Help
Potholes, frost heaves, and uneven pavement are a normal part of driving on Long Island, especially after winter. That kind of repeated impact accelerates wear on suspension bushings and links faster than smoother roads would.
Diagnosing It Properly
Because several different components can cause a similar clunk, a proper diagnosis involves inspecting the suspension under the vehicle and, often, physically testing components by hand to find exactly which part has play in it.
A clunk over bumps is worth having looked at before it progresses. See our suspension repair page for what's involved.
