I just had the same problem but on the passenger side. My mechanic replaced the sway bar and now the knock is gone.
112 dollars parts and labor. So, find a good mechanic that will look out for you in that price range.
Sounds like the rubbers are going in your shock absorbers.
possibly hitting the front bumper
If its a ka thunk sound even on small bumps,Its most likely your STRUT MOUNTS.
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.
Clunking/knocking sound felt though steering wheel and floor when turning and going over bumps at low speeds.
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.
I would check the suspension bushings, if one of them is worn it would cause a knocking noise.
Most likely you need a new strut
I only know from experience that it is the rear sway bar, it took me forever to figure it out but that is what is wrong. The rubber O ring foes bead and it is then metal on metal that you hear when you go over the bump!!
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.
NO. A knocking noise in the engine is a problem in the engine.
