Blue, you might not want to press your luck with those axles. Those sound like mobile home axles, and they'll take a load, but when you break an axle and tear off the spring hangers; what a mess they'll make. I escorted a mobile home one time that ripped the axle clear out from under the frame when the driver braked and it went up thru the floor into the back bedroom of the coach. Whew, what a mess that was, all over a 2 lane highway.
