Scary?: Rotors slightly contacting dust shields during hard corner (wheel bearings)

If you do have any play, you will have to determine if it is bearings or ball joints/ bushings/ steering components as cause
I thought my bearings were really loose, turns out it's the entire 55 year old suspension, bearings were set perfect.

To prove this snug up the bearings so there is noticable drag on the bearing and give it the movement tests. If you feel / hear clunking it suspension. Then reset bearings and and plan for a suspension rebuild.
