Broke a tooth off a spider gear in my front ARB. Should I run it?

ARB? I am confused. Though i will admit i don't know much about ARB's internally, i did not even know they had spider gears
ARB's have spider gears (about the only thing that makes them weaker than a detroit), they use the compressed air to lock one of the side gears, thereby locking the differential. I would replace it, assuming you already found the tooth in your diff (before it blew up the R&P 
), it will cause problems down the road. Better to replace a $25 (guessing) spider gear than a whole new ARB, diff, install, etc.

Thatks for the info on the guts of the ARB. I will have to look into that and educate myself a little bit

Yeah, during a little more investigation I found another broke tooth on the same gear. So I will be replacing it now.
