Every time I go over a bump I hear a knocking noise coming from the front and back end of my car. I've had all struts replaced with KYB strut plus and the issue still remains. My sway bar has a crack in it so I don't know if that is my issue for the front or not but the back I still have no clue. Would my car happen to have both shocks and struts that I need to check out?

Good morning,

Were the strut mounts replaced when the struts were installed? That is common.

Yes, the sway bar can be the noise. Replace that.

Cars either have struts or shocks. They do not have both.
