Alright here's the deal. We got a frame package from Total Cost Involved with a Ford 9" in it. I bolted the four bar together and got the rear end in. With the housing centered in the frame the pinion is 1 and 1/2 inches off to the passenger side. According to the dealer this is the way it's suppose to be. Does this throw off the driveshaft angle? Will this cause a vibration? Thanks!
