How do I Keep wheels on da truck?

The wheels on the bus go round and round, round and round ... that's all fine and dandy. Problem is they are not connect to the freaking truck! I used image points and physics behavior for the revolute points. See, It works when I don't have scrollTo enabled. Its perfect until you go out the side of the screen. So I created a separate object and set scrollto to that. same result. only way for truck to work right is to abandon scrollto and try it manually.

Any thoughts? HELP!?

You have your wheels on the non-scrolling UI layer - move them to the same layer as the truck body.

OMG! Im an idiot.I spent hours on that! Awesome catch and thank you. I guess i "Got wrapped around the axle" LOL
