If it is the red mesurement that means I have an 8.8 inch rear end. How ever I just replaced my outter axle bearings and ordered some from rock auto. The 8.8" wheel bearings from rock auto were too big to fit, so thinking that roch auto screwed up, I went to get some at auto zone. Auto zone had 8.8" wheel bearings but they were the same size as the rock auto ones. Instead, the 7.5" wheel bearing from auto zone was the right size. So apparently I have a 7.5" axle with an 8.5" ring gear. What is wrong here?
