Both of these designs look really cool.
Although, I think the reason you had such great difficulty is that this design creates a huge amount of "scrubbing" force when trying to turn. This extra friction is excellent when going straight, but adds a LOT of extra stress on the drive train once you start turning. Just to demonstrate my point: A dropped center wheel system, whether 2, 4 or 6 wheel drive, overcomes this because it shortens the wheelbase while maintaining a wide track. You get a much greater moment of inertia to overcome the "scrubbing" forces with that type of drive train.
