I once dropped a 24-105L, but Canon could not fix it. :-((They said it was terminal, it has passed away, as dead as a dodo....It fell about 170 meter into the rocks, all I had was a little pile of glass and a few rings.

Test for lens element alignment issues, tape five printed pages on a wall and square your camera to it, space the pages so they are in the center and each corner of your frame and then make teat shots at all focal lengths wide open, either move the camera or the pages to keep them in he corners. If you have alignment issues the pages will have very different sharpnesses.If you have an alignment issue Canon can fix it for a reasonable amount, but you have to send it in to them for a quote.Yup.......teat shots....
