I had to go check. The new bag has 100 balls in it so I'm fine. Maybe I lost some of them when I cleaned it up many moons ago. It was never on the road after that. These balls were in a box with a horn button, upper bearing, and related parts. Maybe I bought them then and never put them in. I think spec calls out for a .280 ball. I measured the old balls at .280-.281 and the new balls at a consistent .281 and round. the old balls ran about .0005 out of round. I didn't get the mic's out and just used a decent set of digital calipers. I measured a consistent .005 of play in the ball nut in all directions before I took it apart. I'm going to put the new balls in and see what I come up with. Those 11 missing balls could be important at 165 MPH. Thank you for your help.
