Why does my suspension clunk when I hit a bump?

The rod’s bushings are a likely source of a clunking noise. Worn-out shocks or struts are also common culprits here. When the internal hydraulics wear out, the piston will move without the proper resistance and stop short when you hit a bump. With shocks, another thing to check for is loose or dried-out mounting bushings.

What kind of problems do worn suspension bushings cause?

Like the cartilage that protects knees and elbows, when bushings wear, it puts more stress on the joints and connected parts. Like bone-on-bone contact, worn bushings can allow metal-on-metal contact. Worn control-arm bushings can allow the vehicle’s front end to slip out of alignment and cause premature tire wear.

What causes suspension bushings to crack and crack?

They wear and crack from friction, age, heat, exposure to road salt and lubricants, and the stress of frequent movement and weight loads. Like the cartilage that protects knees and elbows, when bushings wear, it puts more stress on the joints and connected parts. Like bone-on-bone contact, worn bushings can allow metal-on-metal contact.
