When it's said not to jack under an axle, it really means directly on the tube. How else would one place a jack if not under the spring pack?

ONE wheel? I jack under the u-bolt or spring plate. Wheel service only, do not get under the trailer.
ALL wheels? Lift by the frame.

I have seen a few cases, of people actually putting their floor jack in an obvious wrong part of the axle tube. One case, two floor jacks, one under each axle of a fifth wheel, landing legs down, and the jacks placed between wheels and axle centers. He was packing bearings, too late anyway, so I didn't comment on his placement of jacks, lifting the whole side, with landing legs down.

There is quite a number of adapters for bottle jacks, that will cradle the axle tube, in the U-bolt area. I just made a wooden block, pictured in the recent travel trailer section, asking similar question. Works good for me!

Who the HE!! said NOT to jack under the spring pack???

This tho is by far a better option especially alongside the road.

Oh yea the RV weighs 19k. I have also used on my 24k DRV.

I believe if you do some checking, it's the manufacturers that say not to jack up the trailer by the axles and use the frame instead. But, IMO, that is a simple CYA. If they said it was okay to use the axle, then some nimrod would end up jacking in the middle of the axle so they could lift both sides, or some other moronic reason, and then complain when the axle bends: "But it said I could use the axle to jack up the trailer. It's not my fault".

I find the frame easier to access than what is behind a wheel.

I've never heard anyone say not to use the spring perch; on the contrary I've always heard to use the spring perch as opposed to using the axle tube itself.

I know this is all about jacking rigs with leaf springs... That's why I like my torsion suspension setups I've had on the only 2 rigs I've owned for the last 20 years..

This is my old 2003 Prowler Lynx TT. What you don't see in the pic is the jack stands on either side on the frame as well. The bottle jack is just there to get the tires off the ground initially and then I put the stands under and release the jack so it's just there to jack up again to remove the stands..

Anyway, I've done the same on the Rockwood, I've just gotten a larger bottle jack cause I needed more extension on the pistons..

And NO, the frame is NOT bending... It's just the way the picture came out.. [emoticon]
