Torque is 115 NM, or about 80-85 FT/lb.
When you pull the hub, the bearings and grease can be exposed to
dirt and contamination. Cleaning and repacking is the ultimate solution, but the three times I have done mine, I just was very careful pulling the rotor/hub off, then taped off each end of the hub to keep the grease clean.
Use your own judgement here, if you think any dirt got in, clean and repack.
Otherwise, check the race surfaces for any wear, re-smear the grease and move on.
Bearing adjustment is supposed to be done with a dial indicator, but I tried that method, and felt a lot more confortable with the 100-year-old method. I put the wheel on, snug the nut up good until all play is gone. Then back off a bit, grab the tire at top/bottom and rock it, and back the nut off just enough to discern a tad of play.

Cheers,
