I ended up with a spare 2 1/8" socket, that I'm willing to loan out. It's made of a black hardened resin, and it worked fine for me when I serviced my front rotors/bearings. And, it's 3/8" drive, so you'll need an adapter if you want to use a 1/2" torque wrench.

PM me, and we'll see about shipping the "loaner"...
