Front Sagging Sound When Slowly Going Over A SpeedbumpUPDATE

GoRomeo · 10-24-2025, 06:50 PM

Anyone here experienced this before? Its not a clunking.noise either. I replaced with new shocks 2 years ago. My tire guy did a quick look underneath but did not see anything abnormal. My rear is fine.

No issues when driving other than going thru a speedbump near my house 😄. Car has about 120k miles 135i M sport suspension. I'm sure I'm due for suspension refresh. What should I replace first?

Thanks in advance!

Like creaking springs/door hinge sound?

🤔 More like woosh sound not sure how to describe it. Weird because it does it only when the 2 wheels go at the same time through the speed bump. If I only do 1 wheel at the time ot doesn’t do it.

Maybe you are describing it better than me 😆. Did this happen to you? What did you do about it? I need to do a closer look underneath there for sure.

UPDATE :

For those who care, I ve noticed that the fron sound I was experiencing at times is everytime I wash the car? Would this make any sense? Seems like something in the front suspension or something gets wet and the sound is more pronounced?

It has been over a week since I last washed my car and now there is hardly or no sagging sound in the front suspension going over speed bumps like I was experiencing.

Anyone else agrees with me?
