I replaced the rear wheel bearings but am not satisfied with the results. I'm guessing it might be operator error... Before assembly I did a visual check on the bearing mount surfaces and verified that the axle bearing was well seated on the shaft prior to assembly. I tightened axle nuts down to spec, (200 ft-lbs), but both axles feel a bit "stiff" and do not rotate that freely. My manual gives a axle-nut torque spec of 181 to 239 ft-lbs, but also gives a "preload" spec of 3.9 in-lb. I'm assuming this 3.9 in-lb is the maximum rotational resistance? Torque required to (slowly) rotate the hub is at the upper limit of about 4 in-lbs, but feels too stiff to me. I packed the bearings with "black" disc brake wheel bearing grease, (what I already had in the garage). End play is almost non-existent, but if I loosen up the axle nut and lightly tap the axle end to remove a bit of bearing pre-load, end play increases to about 0.015", which is outside the 0.005" spec. At this end play, rotational resistance is about 2 in-lbs. Thing is, I can't seem to get a reasonable end-play less than 0.015" without it becoming "stiff". This seems to be it's "happy place". Any thoughts?
