Torsion axles causing blowouts?

While checking my axle bearings after our trip to Wyoming, I noticed that when I jacked up the driver's side of the camper, the rear tire came off the ground long before the front. There ended up to be about an inch difference.

Now I wonder, does this mean that the front tire is taking more of the load than the back? Once loaded, these rubber torsion axles don't move a heck of a lot, and an inch is a big difference.

I suppose the only way to check for sure is to go to a scale, and weigh each tire individually.
But if the "weak" axle is transferring weight to the other, that could mean that tire is over-loaded which might result in a failure at some point.

That is one thing that always bothered me about rubber torsion axles, the inability to share the load like a regular spring suspension does.

Bakken I think the issue of one raising before the other attributes to more weight for of axles then aft. Imo respectively.
Thoughts.

turbo, I jacked the camper up on the axle subframe, which lits both axles at the same time. What I noticed is that the rear tire sits higher when right off the ground, completely unloaded.
What I am wondering about is if this equates to a difference in what load that tire carries when back down on the ground.
JFYI, the passenger side is not like this, with both tires coming off the ground at the same time. And I don't remember this issue before, so I am wondering if that one axle end is failing?

You know, if I didn't do any maintenance, I would never notice these things!
Doh!

You don't have this happening on one of the axles do you?

Member Daisy Boykin brought this up a couple of years ago. Here's the link... Look at your 8285ws axles ??

Alko or FR never answered why there's a slotted hole/mounting which would allow the axles to rotate. I fixed my front axle...the rear was OK.

When Sidney (Daisy Boykin) posted that, I put an extra bolt in my axles, and made sure they were plenty tight. My axles are Lipperts with a bit of a different mounting bracket which allowed me to install the backup bolt.

That was fixed as soon as we got the camper home, bolted it up vertically through the camper frame. They ain't goin nowhere after that!
But I will have to check the rubbers as turbo suggested.
