I have two master setup bearing kits (one for Dana 44's the other for Dana 30's). Each kit contains two carrier bearings and two pinion bearings, the insides of the bearings are slightly oversized which allows you to slide them on and off of the carrier/ pinion during setup and shimming of the diff. These are used only for setting up differentials to the proper specs, you cannot run these bearings. These are made by precision, and each master setup kit sells new for $130. i have used each kit once (to install new gear in my CJ), so they re practically new. I am asking $100 for each kit which (the dana 30 kit comes in one box and the dana 44 kit comes in 2). Click this link for pics
