I am curious as if there is another way other than the way I did it. I saw a tiny 1/4" drive that might have worked, but then I don't think it would have been high enough foot pounds, and I don't think you can get a 1/4" drive socket for 9/16. I am guessing that at the factory they had specific torque tools just for those types of applications. Sort of like those ratchet box end wrenches you can buy.
