    Never heard of that one...are you SURE it's not loosening when you tighten the wheel?

    Are you making sure the sprocket is threaded all the way in when you're tightening the bearings? Don't forget there are three bearings in a coaster, you need to adjust the brake arm side (which adjusts the main bearings) then the sprocket bearing cone that only really works when going from braking to pedaling.

    i had a bendix hub that kept doing that. found out it wasn't the bearings at all. the spoke flange broke off the hub completely.

    hopefully that's not your problem.

    check for a stripped axle where the cones are, and check the threads on the cones, too.
