Noise after Strut replacement

Hello. I have 2011 prius 218k miles and learned something I thought someone might benefit from after rebuilding suspension.

So I replaced struts with rebuild and had a bong kinda noise happening when going over parking lot speed bumps from left front struts. Apparently the shape of the spring in aftermarket strut is so different it would tap the strut tower in the body.

My solution was hammer to place spring was hitting.

Anyone interested in details I'll elaborate.
