To check you wheel run out, jack the car up and mount a piece of chalk on a jack stand using duct tape. With the chalk in contact with the center of the tire turn the wheel all the way around. You should be able to see what the run out is by looking at the line.
Re spindle bolts, don't get them too tight! If you do, it can put a pinch on the spindles and when you turn it will not want to come back to center because there is too much drag. I did this a few months back, not fun when the car wanted to keep going left or right.
Check your hub bolts, with age and dryness the spokes get loose between the flanges.
If you tighten them, don't get over zealous, just make them tight.
