well I noticed the rear diff was locking up, grinding. and well...................... I took it apart and the pinon bearings are shot. There is a special hex type socket it looks like that you have to have to remove the pinon bearing. I am wondering if anyone knows what size it is or where I can get one?
thanks

 

anyone? ????????

 

oh yea the nut im talking about looks like it holds the bearings/pinon shaft in, its probly 2" or so round and slides over the pinon shaft.

PLEASE HELP!!!!
