When you put it all back together,be sure no to tighten up the screws and bolts before you perfectly align the rubberized gaskets.I had to re align few times.If I remember well,you shouldn't tighten the screw that goes into the carrier(it has a tiny plastic washer) all the way.Otherwise the hex gets into the wrong angle and you won't be able to tighten it well because of a difficult access,unless you have a flex bit.
So hex goes first,after align the gaskets and then tighten all up.
