Actually the crown nut didn’t move, but the entire wheel/caliper and axel did. It’s a 2008 E2 GEM, _ **wheel wobble** _ on driver’s front wheel (again). **Seriously loose** with about an inch of play at top and bottom. Pulled off wheel and caliper, cleaned, greased, torqued and tightened the crown nut. Blue Locktight and a new cotter key added. ‘All Good’, just like the time before. Why does it loosen. The Crown nut doesn’t move. I did replace the wheel bearings in the hub. Perhaps they were not pressed ‘home’ and are migrating outward? Bearings came from NEV. ‘_Don’t look at them, look at me”, but what could it be_?

Check the cast aluminum hub, see if its cracked.

Also, torque settings are dry thread.

Thanks JJ. Hub is steel. Followed your suggestion and dry thread torqued. The ‘sealed bearings’ I got came apart in my hands before installation. Question there somewhere. For now it’s an easy to monitor thing I’ll keep checking. Next step probably is to re-replace the wheel bearings (half shaft carrier bearings) and after cleaning and inspection next time I’m in there. For now it looks good. Again!

I may have been thinking of a different year or an aftermarket replacemt when i thought of the aluminum parts.

Are these the double row bearings? My 10 had those. I recall lots of internal clearance.

Fwiw, unless indicated otherwise, tightning torque values are always dry thread.
