Default Thumping noise

I hear this thumping noise up to 70 km/h, but a lot if I drive slow around 5-10kmh and you can hear and feel it very well, especially on uneven cracked roads. I drove over many small,medium and big speed bumps to test it out at all speed and I don't hear a thing. I had a blown front strut last year and I replaced all 4 a few months ago to brand new OEM ones at the dealer but a blown strut thump I had was bad and you can hear it at very turn and bump. This noise is not a thunderous thump but more of a multiple mini ones. I dont hear it on even roads on a quiet street. =/

Sounds like you could have a rubber suspension bushing going bad. Inspect all of the rubber mounting bushings on the front suspension. Look for torn or cracked rubber.

To me it sounds like a bad tire, the faster you drive the soon it quiets down correct? Try rotating your tires and if the noise gets shifted then thats your issue. You never know you might just have a nail or a screw in one of them.

That’s correct, I’ll try rotating it too and see.

Did a inspection at the dealer and checked all bushings, suspension components, rods, rotated tires, arms and they're all in good shape, we went for a ride and tech said the noise would probably coming from strut mount, but said it wasn't too serious. Guess I'll drive a bit more and see if the noise becomes worse or not. But this rattle/thump noise is not pleasant, guess I'll just turn my radio on a bit louder lol.
