If you lift by the axle end, between the U bolts, you must use a half-circle adapter. The flat top of jack could damage the thin wall axle tube. A second choice is to use a block of wood between the jack and the underside of the U bolts.

Lifting by the axle end means that a 2” lift will get the tire off the ground without tipping the trailer. Lifting by the trailer frame (as usually recommended by the axle manufacturers) means that you will need blocking under the jack to get it high enough, will have to lift 4” or more because of the suspension relaxing and will be significantly tipping the trailer towards the other side.

Thanks so much for the timely response. Robs pdf post answered my questions and put my mind at ease as to where to lift up on the axles. Much thanks to you and to Rob for sharing his strategy !!!😃

Here is a link to a bottle jack cradle that you can weld to the top of a bottle jack.

Cate&Rob Is there any risk of bending the axle by doing this?

Cate&Rob Is there any risk of bending the axle by doing this?

If anything . . . there would be less risk of bending the axles when sitting on the stands than when sitting on the tires (but, this would be a very slight difference.) The weight of the trailer is supported by the springs attached to the axles. The tires are slightly outboard of this, so there would be a small bending moment. If the axles stands are places between the U bolts, they are directly under the springs and there is absolutely no bending moment on the axle.

If by "bending" you mean "denting" the axles tube, it is important to have a saddle on the top of the stand that nests uniformly to the axle tube with no flat sections against the round axle tube. This duplicates the top saddle welded to the axle tube for the spring seat and the tightly fitted U bolts that go around the axle tube.

Cate&Rob I guess another and important question - how long does a trailer need to sit before it develops flat spots / damage to the tires? I realize this question is one of those it depends on the weight and the specific tire and ply of the tire....but wonder if anyone knows a general answer.

The reason I ask - is you are doing this just to save the tires right?

I expect that every tire manufacturer will advise that extended time sitting stationary and carrying weight is not good for their tires. I store with weight off the tires to preserve the tires, but also this allows spinning the wheels every once in a while so the brakes don’t sit in one place and pulling the hubs for bearing repack is easy.

RGEarley -- when the forum software was uploaded a lot of the links inside of posts were somehow removed (or not reinserted?). Thanks for the note--fixed the post.

During storage I jack her up and spin the wheels every other month. No specific reason for the every other month timing. Just feels about right. And has been working good for 7 years of trailer ownership.
