Where to jack

Ha, good one.:)

hmmm. three different 5th wheel rv trailers...one TT...and maybe 12-13 GN flatedecks.....three cargo trailers and never had a need to jack the whole trailer off the ground. Anywaze.....

I use a shorty hyd jack under the axle tube next to the U bolts when servicing/changing a flat on one wheel. The jack is a truckers special that has a adapter that fits over the top of the jack and cradles the axle tube...no slips in any terrain even with big rigs blasting by at 80 mph.
Std leaf spring suspension axle tubes (1750 lb to 10k lb axles) will not spot crush/dent jacking from a single spot. All this method does is lift one end of the axle.

Now, I have jacked one side from the frame and removed 2 or 3 or 4 wheels on that side depending on tandem/triaxle or tandem duals. If the trailer was long I used two jack next to the farthest spring hangers for a lift on one side. I bent the frame on a fully loaded 40' GN triaxle by lifting from the frame from a single point between the axles while changing a flat tire on the side of the road. Lesson learned. Thats when I found the 12t shorty hyd jack made for jacking from the axle tube.

You need a lot of cribbing to lift all the tires off the surface for removing all the wheels. When its that high be safe and use safety jacks or RR ties placed where they won't roll and drop the trailer. Be safe and don't take chances.

Don't do what my silly bil did and leave the trailer hooked to his truck. After jacking all 4 off the pavement his wife said he was so proud.....until he called me and asked if he could use my truck to run his tires to the tire shop.

No thanks.
The kids as discount started jacking mine up by the middle of the axle.
Then they tried to use the rubber portion of my Dexter kit.
I had to school them on how to lift a heavy, triple axle toy hauler.
Always by the frame is how I lift mine.

With low profile trailer the frame is the place to jack.

I don't jack the axles I jack up the frame or https://www.walmart.com/ip/BISupply-Tandem-Wheel-Ramp-5-5-Inch-Trailer-Wheel-Jack-Flat-Tire-Ramp-1-Pk/966162365?wmlspartner=wmtlabs&adid=22222222222000000000&wmlspartner=wmtlabs&wl0=e&wl1=o&wl2=c&wl3=10352200394&wl4=pla-1103028060075:aud-807615483&wl12=966162365_10000000498&wl14=trailer%20ramp%20jack%20wood&veh=sem&msclkid=9abbf8e24ba91a1c1ff2a5229dd8d952

I use my level system to raise one side, put jack stands on each axle at the u-bolt, then put a 20 ton jack on the frame as additional support in case of hydraulic failure. We're full-timers and I change tires by side so this works out great for me. I just take the wheels to a shop and have them mount and balance the new tires

Thanks guys.

I put the jack directly under the axle.

You can bend the axle that way. Especially if you get away from the wheel.

If you are lifting by the frame or with hydraylic levelers, do not lift all four wheels off the ground at one time. You could flip the shackles and that is a pain in the %%%%% to fix.

I would not jack a wheel up like in the pictures unless I had a jack with a large enough head to fit over both U bolts or some other type of pad. There is too much weight on a very small area the way the picture shows. I suspect that is why the axle mfg recommends using the frame.
