    I've noticed that my popup seems to be sitting lower to the ground than it used to. This is evident by the scraping of the underside as I back the camper into my driveway. The popup is a 1992 Starcraft Starflyer, and has a Dexter torson-flex axle. As far as I know, I have not overloaded the weight rating of the axle. The camper has the original wheel and tire size, so I know that isn't a factor. Has anyone else experienced this?
    Thanks!

    The axles themselves, no. But the springs do wear out. Whether they are leaf springs or rubber as in your torson axle. Over time the rubber breaks down and wears out, thus making it sag.

    The axle on my Bayside did 'flatten out' probably by being overloaded by the PO. (Upgraded to a 5k rated axle and did the spring over conversion.)

    Yes, torsion axles do get tired. The rubber either wears out and the trailer sits lower or the rubber gets hard and no longer moves, which cause a rough ride for the trailer.

    The rubber in the axle on our '15 TT deteriorated after 3 years. The spring shop that made our new axle said that it's not unusual to have that happen in our climate. Since it's common for rubber and rubber-type materials to crack and die in a fairly short time, I believe him. (We just had to replace the rubber latches on our Canyon cooler - they sent new ones under warranty - after maybe 5 years.)

    A torflex axle from 1992 could easily be worn out.

    for longevity and no sag stick with leaf springs, they are great until they (infrequently) break

    It's actually not that uncommon to see broken leafs. I would bet that if you were to take the time and really look you would find about 1 in 20 would have at least a cracked lead. It usually happens at the locating pin. It may only be on one side and never completely break but it's there. Sag will happen as well with leafs but it should take a pretty long time. Every time they flex they lose just a bit of height. Not noticeable but over time it adds up.

    Most of the replies here are not relevant. The original poster says he has a torsion axle. They don't have springs, leaf or otherwise, they have "rubber bands". These bands do indeed get "tired" and will require the axle to be replaced.

    I know, because I just replaced mine this spring for this reason.

    Just this week, my buddy had both front spring eyes break on a 7 x 10 utility trailer. It was unloaded when it happened, too....Never seen that before
