Has anyone experienced their hubs getting warm? I just drove some after my front axle rebuild and the hubs seem a trifle warm. How warm should they be? Is it possibe I got the preload too tight or is there an adjustment period?

Anything above comfortable to touch I would be worried about... Did you install new wheel bearings?
Should not be warm at all after a repack. MIke
agreed. you probably tightened the bearing/hub nut too much.

I used to old ones. they looked ok. Would that have an effect?
Check the brakes too. They could be dragging some.
For the most part wheel bearings should be at most 20 or so degrees above ambient temperature after heavy use. At the surface of the hub you will barely notice it. More than likely any heat you feel there is due to the brakes unless the bearing is lacking lube or is set to tight.

I rebuilt my front end last summer and not using a torque wrench had some concerns.
If the hub is too hot to touch then it can't be good. Do you have hot bearing grease coming out? Do the hubs turn easy enough? Are the hubs locked? Might want to go back and check the bearings and not crank down on the nut so tight.

they are warm after a 5 mile freeway ride, not too hot to touch. I tightened to fsm spec with a torque wrench, then set preload to fsm spec using a good quality fish scale. No grease coming out. I will watch them for a bit. the brakes are new and may be causing the warmth.
Depending on your wheels, you may be able to use a non contact thermometer to figure out what parts are the hottest.
