BDW,

That was it, you hit the nail on the head, I was re-using the 1970 dust shield from the 10.87 rotors and the new 11.75 rotors were hitting the center lip and not letting them slide all the way back!! Thanks, I was about to buy another set of inner bearings thinking the Timkens were too large. Crazy, I could not tell from spinning the rotor that it was not set all the way back on the bearing and was riding on the flange. Thanks again!
