I would have the front wheel balanced .
I was just thinking about this, this morning, seeing as you have to remove the caliper(s) to get the wheel balanced, with the calipers removed, but with the axle nut still tight, could you balance the front wheel, while still installed on the bike .
I came up with this yesterday, while I was working on the project LS, after having the tire replaced, I added two new rotors, and replaced a nut holding the rotor to the wheel, it's a larger all metal nut, as compared to the original plastic/fiber type lock-nut .
