Tire inflation may be an issue as I'm not sure what to inflate them to. They are brand new tires. I may have them underinflated. It does sound like a transmission noise or a front end noise, it's hard to distinguish where it is coming from sometimes. The TOD continues to surge, I think I may bring it in to the dealer and have them hook it up and tell me if they get anything from it. I don't have any lift at all, and the torsion bars are untouched.
