Thanks Robbie. There is indeed some of the thread from the adjustment screw left. When I sent the box in to them there was almost 0 preload. When I got it back there was definitely more but I didn't really check it for spec, just installed it.
I'll adjust it a bit more and see what happens, thanks for the input!
