Sharp Eye? Help a Fellow School Bus Mechanic/Blogger

School mechanic and blogger John Wheelan turns to readers this week for advice. He's just removed the front end of a Thomas HDX Pusher because the bus wanders when the brakes are applied. But he can't figure out what's going on. Check out his blog for more details and see if you can offer some advice. FYI: It's not the brakes. He already tested that.
