As of lately my car started to make thumping/knocking sounds whilst driving over speed bumps (at regular speed) I drive a 2001 renault laguna 1.8 16v with about 218,000km (about 135500 miles) on the clock.
It doesn't happen while driving on flat road, i can only hear it when driving over speed bumps.
it kind of sounds like someone is giving a mean knock on a door.
does this mean that my rear suspension is bad?
UPDATE: I took a look at the back of my car (even removed the wheels) And couldnt really pull a conclusion myself. I took it to my local garage and they told me the shockbreakers(absorbers) were busted. They have been fixed and the sound is now gone. Thanks for all the suggestions.
