Scary?: Rotors slightly contacting dust shields during hard corner (wheel bearings)
There is a torque spec for the nut IIRC 90 inch pounds. Check your FSM
That being said, what I have always done:
- grease things up just the way the FAM shows
- assemble
- spin the tire/wheel while tightening the nut, this insures that there is no excessive grease between the roller and the cup
- go a tad over finger tight, then back it off till there is a slight amount of noticable play
- see how the nut and keeper line up
- tighten a tad or loosen a tad to align
- then cotter pin.
This procedure has worked well for every car I have owned over 50 years.
The wheel, rotor and caliper will be mostly moving together, slight movement between the rotor and caliper due to flex and the bearings, which is normal and helps move the pad away from the rotor so it is not always dragging.
I suspect the dust shield as you pointed out, I had the same on my KH front discs.
I was able to move it away from the rotor on the car with the wheel attached. If it has 1/2 inch clearance it should not touch
ALL THAT BEING SAID...
if you are really loading up the suspension with hard cornering, it can't hurt to pull and inspect things
