Yes, that would be consistent with a problem with the rollers. The rollers don't spin when you are driving straight forward. They spin a LOT when you are strafing.

To rule out the weight distribution as the cause of the problem, try adding some temporary weight to the lighter end of the vehicle and see if there is any improvement.
