changing tire

On the axle right under the spring perch is best.

I asked Dexter about this and this is there answer, this is the same for all axles.

^^^^^^Seems like it would be fine to jack under the spring perch, since you're not lifting or supporting the trailer, just raising a wheel to change a tire. That's how I've changed my tires, and worked on the brakes too. Just don't put the jack under an unsupported part of the axle. You don't want to bend anything.

The issue with 5ers is the frame is already so far off the ground, that getting a jack to lift on frame is a bit in stable.

always on the spring perch. I have watched tire shops jack here so if at home that is where I jack from. If I am on the road I drive up on blocks and save myself the hassle of crawling under if I can

Lawyerese CYA policy for the complete idiots that would be better off having a FW dropped on them. Jack under the spring perches and you'll be fine.

Change a single tire I jack on the U-bolt.
Major work I jack on the frame and support with four 12 ton jack stands under the frame.

My experience has been 2 floor jacks under each spring perch on 1 side; swap tires; do the other side. After 4 sets of tires, I have no axle issues. I also jack each wheel up every year to check and grease bearings the same way. (shrug)

MFGs state...Jack under frame.
CYA lawyerese so that some fool doesn't jack up trailer under axle and bend it then file 'warranty claim' (because mfg. has no control over fools)

Logic....
Trailer is attached to axles by leaf springs and U bolts at spring perch on axles.
Trailer axle weight is supported at that spring perch

Using a jack under axle AT the spring perch will not result in bending the axle.

Tire shop will jack up trailer using 2 floor jacks ...one under each axle at spring perch on one side. R&R both tires then do the other side.

They are not going to crawl up under trailer dragging a floor jack and jack it up in middle of axle when it would be damaged.
Too much of a hassle, too much time involved, too big of an effort.
All of which a tire shop is NOT interested in doing

Relax...

My spring perches are on top of the axle.
