Wheel bearings: I don't remember if I put news one in or not, I'll have to check my records on that.
Wheel balancing: One is balance on both sides, because the problem started after I had a new valve put on that wheel, so I re-balanced it. The other wheel is balanced on the inside only, but I didn't have a problem until that valve. I don't think it is the problem, because I balanced it 3 times, and it doesn't shake going straight.
Inner tie rods/tires: When i replaced the outer tie rods, cleaned, adjusted, and added new boots to the rack, the inner tie rods seemed to be solid.
The tires are new.
