Axel clunk

[Fyouberg]

When jacking up my 2018 23RL JayFeather to rotate the tires, I had something scary happen. The right side was up on a floor jack, I had loosened the lug nuts on the left side and was in the process of lifting it up enough to finish loosening the nuts and removing the tires when the rear axel clunked and dropped about one half inch. Jack was ok. Other side of the trailer was ok and U bolts and leaf springs looked fine on both sides. It did the same thing when lowering the left side down on the tires. Does anyone know what might have been going on? Was a leaf spring shifting? Something else?

Does your tt have tandem axles? I suspect the leaf springs just adjusted when the load changed. The "equalizer" between the two springs are on a pivot point, and the two springs are connected together. It's kinda like a see-saw. Took the weight off of one axle, and the other axle went down as it weighed more.

Yes. Tandem axels. I did have the floor jack in front of the right front axel and was jacking behind the left rear axel.
