Was going to rebuild the rear diff but tweeked the threads on the pinion just a little. Now I'm going to just buy a used rear end. My question is do I have traction control or not. The pinion gear has 10 bolts and is 3.55 ratio. Found some online for a good price but the have a with and without traction control option. Would I have a button in the cab to turn the traction control on and off? Thank you for your help!
