possibly hitting the front bumper
Most likely you need a new strut
I would check the suspension bushings, if one of them is worn it would cause a knocking noise.
Not extremely, but it will cause a noise (sometimes) when going over bumps and premature tire wear.
Sounds like the rubbers are going in your shock absorbers.
Sounds like the shock bushings are worn out are loose.
Clunking/knocking sound felt though steering wheel and floor when turning and going over bumps at low speeds.
Little rubber parts that help to cushion a car's suspension system, if they wear out you can hear a knocking noise when going over bumps.
Both ends
Depends on where the noise is originating from, a suspension component, engine (top or bottom?), steering knocking when turning, going over bumps, etc. You need to provide more details before I can point you in the right direction.
Can be a loose shock, or loose suspension parts. Can also be loose exhaust system parts. I had a car that made a front-end knocking sound on bumps. Any little bump would do it. Turned out to be bad struts.
There are many reasons why a car would make noises going over bumps. You need to be more specific about what kind of noise? Rattling? Maybe a loose component under the car, or heat protection plates not mounted properly. If its a knocking it could be your shocks, or cv joints. There are too many possibilities that it could be. Please be more specific.
If your vehicle is squeaking when it goes over bumps, you may need new shocks or struts. The front end of the car wears more quickly than the rear, so the issue usually begins in the front.
