After reading several threads about setting the front wheel bearing end-play using a dial indicator vs. 'doing it by feel' I went ahead and purchased a metric dial indicator and stand. As per the FSM I am looking to set the end play to .01 - .02 mm, however I am a bit nervous about setting the tension too high and am hoping for some reassurance I am doing this correctly...

I currently have the clamping nut pretty tight (in my opinion), meaning I can't feel any play in the hub but I can still turn the rotor with one hand. When I set up the dial indicator against the hub and push/pull I can still see the movement on the indicator of about .20 mm.

So assuming I am using the dial indicator correctly I should still need tighten the clamp, however as mentioned it is already pretty tight and I would have to use a large wrench to make it tighter than it already is (which is why I'm nervous that I am over tightening).

Can anyone offer any helpful insight into whether the clamping nut should require a fair amount of torque to get the hub tight enough? Or is that an indicator of something else being incorrect?
