Currently changing to discs with the kit from Chevy Duty on my AD. Bearing adapter went on fine (driver's side). Rotor and inner bearing - no problem. Outer bearing won't budge. The directions indicate the " 3/4 portion of the spindle may need to be turned down a few thousandths by a machine shop for the bearing to seat properly." It won't even go on past the threads, let alone seat properly. It feels like the old outer race wore a groove on the spindle which has a lip the new bearing won't pass. I tried to Dremel it down, but it still won't go over it. Should I take the spindle to get professionally turned, or look for new ones, or what?
Frustrated in Detroit.

Methinks you know what you need to do but can't face doing it. The proper procedure would be to pull the spindles off and have them turned at a machine shop. If you had a micrometer, you could mic the spindle on a good, unused area and compare that to the 'book' ID of the new tapered roller bearing. This would confirm what Chevy Duty considers 'a few thousandths'.
A die grinder with a flap wheel and some prudent work might bring the OD down enough to allow the bearing to slide on. I think the fact that inner and outer bearings are so far apart would preclude any alignment problems with the 'hand job'!
There are all kinds of shadetree ways to make things fit and work, but there is only one 'right way', and the right way in this instance requires lots of grunt work. Is it worth it to do it the right way? Could the truck stand a brand new set of king pins to go with the snazzy new disc brakes!

My father in law and I talked about that while we were swearing and I was throwing tools. It makes the most sense to me, but I was hoping somone already had this on a shadetree resume, so to speak. Yep. You've confirmed what I was hoping to avoid, I do believe. One more setback to build character and put another deposit in the "it will all be worth it" account.
Thanks,
Jason
