Bad in that one of the rear trailing arm mounts ended up with a broken screw in it, and all the nice and easy fixes did not work. What is left of the screw is now beneath the aluminum face, and of course any drill bit wants to bend / wander off to the aluminum. I have a helicoil kit coming in tomorrow, and once I know the full size drill bit I can run on it, it will hopefully be stiff enough to not wander, but I am not confident. So a new mount may be needed.

I just had to deal with a m2 screw that had broken off flush in an aluminum scale winch on a friends crawler. Being it was an m2 i really had my doubts getting it out. I used the same method I use on / cars with broken or stripped bolts and screws. I lightly welded it creating a small ball of weld on the end of the screw. Normally from here i would weld on a nut to extract it with but the little ball was more than enough to get a pair of pliers on and simply unscrew it.
Simple method if you know someone with a welder. Took more time turning the welder on than it did to do the job and extract the screw.
