Glad and sad to read this thread. I have what I guess is the same wobble. I thought caused by under inflated front tire, which lead to cupping, which lead to wobble. Or, poorly balanced front tire, assuming dealer or factory balances front tire.

So do the bearings cause the wobble, and hence the cupping, or maybe the cupping cause the bearings to need replacement?

I still have the original equipment front tire, and I think I ran it for some time at 22 psi. I am at 8,200 miles now.

Wonder if when change front tire, should change bearings as well as brake pads.
