Every now and then I get suspension noise that sound like creak (especially when braking hard either by pressing the brakes or letting go of the accelerator suddenly) or sometimes low volume clunk sound when stepping on and letting go of the accelerator in short burst. It's not a constant sound so I'm so bothered by it. But I was wondering if these noises are normal or do you think it's related to the "knocking suspension" issue? I don't really hear noises when going over speed bumps. So I'm not sure it's related to the TOPIX issue on suspension.
