<br>
Is this the idea: when we tighten the lug nuts, we compress the gasket from, say .014" to .010". At .010, the axle center makes contact with the spacer ring and bearing, coming to a stop. There is then .010" between the carrier and axle flange. The gasket takes up the slack - is the compressed gasket strong enough to in effect be a shim between these two parts?<br>
<br>
Michael - maybe when extra-tightening of the lug nuts, the axle flange is also bending slightly to take up this gap.<br>
<br>
Betcha I'm over-thinking this! :-)<br>
