where do you put your jack

I have had to change a couple tires by the side of the road, compliments of Carlisle China ST tires. :) I put my 10 ton bottle jack under the axle U-bolts, but not on the axle tubing itself.

Trying to jack the frame high enough to allow a person to remove the tire would require extensive frame support and a very high lift jack. And I wouldn't do it anyway for fear of putting excessive stress on a single point of the frame.

And yes, my manual says to never use a jack on the axle. IMO another CYA statement insisted upon by the lawyers.

Do you really think the axles are made out of tubing so thin that jacking on the tube will collapse it??? :h

If they were the first bump in the road would bend the axle and the tire would be at a 20 degree angle.

I think the axle tubes are only as thick as they need to be to carry the trailer without being damaged. Now whether that is thick enough to put a jack under and lift is something I don't know, and I don't intend to run the risk of finding out it's not. You do what you want and I'll do as I please, and we'll both be happy.
