Did I screw myself??.......grease on rotor studs

[Toploader]

I do not know if I did a stupid thing that will come back to bite me in the ass, or get me killed

After packing the bearings I dabbed a bit of grease on each of the the rotor studs.......then used an impact gun to tighten all the nuts down. Will that grease in time allow the nuts to walk out??

Adding a lubricant to a torqued fastener alters the accuracy of the amount of torque you have to apply, because the torque effort is not acting against the friction of metal on metal, due to the lubricant.

So it is possible to easily over-torque fasteners when lubricants are used.

But in general, I'd say no, it doesn't make it more likely for the nuts to walk out. I use anti-seize on my lug studs and don't have issues. OTOH I have my wheels off more often than most folks.

I'd sooner be concerned about the overtightening in case you need to change a tire at the side of the road. I'd loosen them and tighten by hand.
I usually put a couple drops of oil on my wheel studs and wipe the stud down to keep rust at bay. I've never had a wheel fall off, or a lugnut loosen, nor have I ever had a problem removing nut due to corrosion.

right, its the ugga-dugga factor at play. 85-105 ft-lb is factory spec. A bit of lube on the threads won't bother it any though. Not even sure the type is overly important, just something oily to keep the lugnuts from rusting to the threads.

I agree with all of the above. I always use some kind of lube on the wheel studs, and I always tighten by hand with a torque wrench to 90ft-lbs, partly because I have aluminum alloy rims. I'd never trust an impact wrench on them, though I would even do the final torque on steel wheels by hand just because.

Thanks to all for your thoughts............guess I can sleep tonight;-)
I used to have a good torque wrench, but somehow can't find it, may have let someone borrow it and never received it back.
Hope I do not have issues because I do indeed have the original aluminum, alloy wheels.

i always use antisieze on the studs.

Yep, resonating all of what everyone else has already said. Been doing it for years with no problems and would never NOT apply anti sneeze or some type of oil to the threads to prevent seizing.

On steels & turbines I use a breaker bar, when the car rocks I call it good.

I have a HF 1/2 torque wrench (inexpensive enough to keep in the car but pretty accurate per some independant tests) for the race wheels @ the track. As previously stated, a little lube is ok.
