a certain logic to it - except the o-ring does the
actual sealing, correct?<br>
<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>
