    I had the coils, a-frames, spindles, etc. pulled off my 70 to install a Mustang front end kit from American Pony Car. Figured what the heck, might as well get replace the inner and outer wheel bearings. Anyway, drove the old races out, tapped the new ones in, packed the bearings, and put everything back together. As I was tightening up and wheel bearing nut I noticed that the nut wasn't going on far enough to allow a cotter pin to go through both side of the spindle (same thing on both sides). Figure there are 3 possibilities:
    1) replacement bearings are too "thick" so the hub isn't going all the way on the spindle (numbers on replacement bearings match numbers on old ones)
    2) races not fully seated in the hubs so the hub isn't going all the way on the spindle (I checked each race with an inspection mirror, all were fully seated)
    3) when reassembling the brake shoes, etc., I did something wrong so the hub/drum can't fully seat on the spindle (looks okay to me)

    Any tips? Am I missing something obvious? Thanks.

    My first thought was to try a different nut, who knows maybe this application uses something different?

    after posting, I reread your post. I intially thought you replaced spindles etc. Now I think you are using the factory mav parts. Are both sides doing the same thing? Have you taken one side apart to totally be sure everything is correct?

    I recently had my bearings replaced and had the same problem.

    I didn't know which to scratch, my head or my a$$. :confused:

    I finally cranked down on the nut in an attempt to seat the race
    in case it wasn't fully seated. It worked!

    I also remembered to put the THICK washer behind the nut. :D

    I don't know if my solution will work for your problem -
    just commenting on what I, personally, had to do.

    Good luck and keep us posted,

    Rick

    All parts, other then bearings, are original.

    Thanks for the ideas, I'll try again this afternoon.

    When I was tightening the backing plate to the splindle, two of the "t" end bolts turned and bent the "cover plate" (for lack of a better term) in toward the spindle. That prevented the hub fully seating on the spindle. Exact same thing on both sides. I turned the t bolts slightly, then bent the plate back -- problem solved.

    Cool Tom!

    A lot of (us) guys don't follow up with their solutions - so
    we're left wondering if/how a problem was resolved.

    Good to hear. Thanks for the post.
