I've got this irritating squeal sound when I ride over speed bumps, already for a few years.
Every time I go to the dealer, they try to fix it, though never fixed it completely. Once they added some kind of lubrication, another time they changed one of the suspension parts. However I still have the issue.
The squealing sound can be heard here:
Any idea what the reason is? I'm going back to the dealer soon and would love to hear some suggestions that so they might fix it.
