I've got a post about this in the TJ tech forum, but I really should've started here. Anybody know a shop that will road force balance my 33" Duratracs until they are right? I just had them balanced for the third time and still got a steering shimmy from 45-55. The last balance was road force actually but I don't know if the guy cared or really kept at it until it was right. He did find one of the tires had too much runout and that one is being replaced. I'm in North Hollywood.
