I use a $30 portable 2 ton floor jack available from Harbor Freight or most any hardware store. I've had a bottle jack kick out too many times due to weight shifting while lifting under a round axle. The floor jack is small and light enough to carry in my storage compartment and feel it is much safer.

Yeah I was leaning towards the floor jack idea because of the reason u mentioned the surface of the bottle jack on the curved axle I don't feel safe. Is the 2 ton jack enough to lift the axle?

A 2-ton bottle jack on the middle axle of a triple axle isn't strong enough to lift the axle without a very large cheater bar, and I wouldn't even try it. I use a 10-ton bottle jack on my triple axle toyhauler and it works very well. I tried a 5-ton before that one, and it struggled to do the job.

And I jack on the U-bolt opposite the plate. No issues so far, but I've only done it a couple times.
