Why does your car rattle when you hit a bump?

Answer 1

It depends if your hearing a click or a rattle. if it's a pretty consistent rattle as you go over a bump or bumpy roads than it's more than likely a blown strut. what happens is the seal in the struts goes and there is no more pressure and things aren't being held in place. the piston rattles of the strut cylinder. now if it's a clicking sound that you hear and it's not constant, just certain bumps and/or your steering wheel or front wheel feels like it's shaking at highway speeds. usually around 50-60 mph then it could be a ball joint. most shops do free estimates if you bring it in and ask them to check it out. if it is a ball joint the you don't want to drive the vehicle till it's fixed. this is serious!! mechanic will tell you the same thing! but either way the both cost about the same to fix.
