I would suggest you not put your vzw address here. Pick another email that you can change and have it forwarded there. Once spamed you can never get rid of it except call VZ and have them change your account.

I agree with Finch. If it is under warranty, swap it out. If it wasn't under warranty and it was my BB, I'd order a new track wheel and I'd do the install myself. I've never come across a repair that I couldn't fix on my own. If you search the forum you'll find a thread that shows where someone took their BB apart and posted pictures of it. I guess I'm just not afraid to take anything apart and put it back together, but that's my nature. Good luck with your endevors.
