Those axles are probably Henschen. Here is a link to my post about the need to replace my axles a couple years ago.
It has a link to some data about Henschen axles. The data is similar to that for a comparable Dexter axle. If the Dexter axle were to be compressed by a full GVWR load and the trailer was raised the drop distance of the wheel should be 2.3". So if your trailer was close to fully loaded, your 2" measurement would be about right. My axles only dropped about 1.5" and the ride was rough so I changed them. If your trailer was empty, something isn't right. Typically, however, when the axles age out the rubber has hardened and they either do not compress as far under load or not relax as far when the load is taken off or both.
