We had to pull two wheels off and replaced them with castors to even get some control. It wasn't pretty.

We did almost the exact same thing our first year (2001), except we (kind of) solved it by covering two of the wheels with duct tape. Admittedly, it did work well enough to win us a regional, although that had more to do with our pushing ability.
