  • Rear Axle: ‘50 champ rear axle

    Hello all,
    Last year , I purchased a replacement axle for the passenger side of my champion whose notch for the woodruff key wasn’t tapered- will this cause any issue?
    the reason I ask is when I take a slow right turn I get a “ clunk noise” from that wheel. I recently measured the end play and it’s .005”. I plan on rechecking the end play again to be sure but wanted to make sure the axle wasn’t contributing to this. If not, any ideas on other things I can check to find what this noise might be? I’ve got new bushings on the leaf springs, ujoints and carrier bearings are new. Nothing loose in the trunk.
    thx,
    Jim

    Jim, the repro axle shaft is fine. The key is there to prevent the axle from spinning inside the hub, it doesn’t control any potential lateral movement.

    Do you have the axle nut torqued down tight enough? Were the axle bearings replaced?

      I have it at 180 foot lb. but I’m going to take it apart and recheck everything again. Your idea is a good possibility.

        Make sure that the key is as far outboard (towards the axle nut/washer) as possible. It must not be too far inboard (towards the differential).

          Thx Roy,. I left it protruding out and let the axle nut push it in. I think
          thats the correct way?

              The frustrating part about this is I don’t hear the noise on every slow right turn I take. In fact it’s probably 1 or 2 out of every 10 turns. I don’t hear it in any other driving situations and it’s not a loud noise. Intermittent problems are the toughest to diagnose in my opinion.
