I'm glad to see you got the busses out but for future reference don't make a hard pull like that in reverse.  If you put enough torque through a diff that way the crown will climb away from the pinion with disastrous effect.  Ask me how I know.

The last thing I would ever want to do is hurt you.
Its the last thing but its still on the list.

Okay, I'll bite. Tell the story. Please? :) Mitch

High flotation truck with 48 x 66 x 25 rubber & an 8 ton load.  23,000# rear axle, 2:1 drop box and an Allison transmission - ie. lots of torque.  He hooked onto a stuck 3-ton truck and pulled it out in reverse.  The diff shop told us afterwards that we shouldn't tow in reverse.  Mind you, if he had towed going forward he would likely have spun an axle so he was pretty well hooped from the moment he decided to hook onto the other truck.
