Rear wheel bearing issues

[doubt at inwave.com (Nate Mellom)]

I did put moderate pressure on them, but just with a 1/2" ratchet, not 
my torque wrench.  I was told I should "seat" them, but I didn't want to 
put too much pressure on them.  I'll pull 'em apart tomorrow and apply 
known torque as suggested.  The races were pressed in with a shop press, 
using correct sized sockets as plungers.  All 4 races are pressed in 
tight and square, fully seated in the rotor.

Completely boggles my brain that the fronts need to be torqued to 63 
quadrillion ton feet, and the rears are teeny tiny finger tight.

Thanks!
Nate
