Replace seals when repack bearings?

FYI, the torque value isn't measured at the hub nut.
Proper preload is set by tightening the hub nut, & measuring resistance at the wheel stud, by using a fishing type scale. (before the caliper is reinstalled)
My personal favorite is a digital one I found at harbor freight.
You can easily get the hub nut tight enough using the same method as described for loosening.

That's true, Dub, but I was just super paranoid about whacking at my hub nut. I tend to be mechanically disinclined and I was worried that I was going to stab or smash something that didn't like that sort of treatment.

I used my torque wrench as I was doing the pre-load on the hubs with the scale, and it came out to about 18-19 ft/lbs for my old, repacked bearings which is a pretty low torque number so a screwdriver and a hammer could easily reach that number.
