Because the same idiot could have balanced both sets of tires..... Your not being very polite to the people giving you suggestions.

I have had cases before where i had to return the car 2 or 3 times before they finally balanced them so i didn't get a shimmy.

Anyways, yes play in the bearings could cause a shimmy, they need to be inspected and if worn they need need to be replaced. If the races and bearings look fine they need to be re-packed and set to the correct tension.
