Dont know about limping on one axle because your springs would pivot. It might could be done, dont know. Im sure someone will be along to comment. I do know that if you lose a hub and you dont have a replacement with you, you can limp on three wheels. This happened to us just this past fall. Dont know what a safe distance to travel in this fashion would be but you can limp in this manner until you can get it fixed. Joe Murray
