2021 No Bo 19.5 bent axle

Not with axles, but bent wheels are somewhat common. Apparently, the way they are packed for shipment to trailer manufacturers makes them easily damaged in transit.

Most trailer axles are marginal at best, banging over a 4" curb probably bent the axle. Consider replacing it with a stronger part if possible.

Yup. Small tires over a curb with a light-wieght axle can easily bend it.

It would be good to figure out what you have now. If you only have a 2200# axle, a 3500# should be an easy upgrade.

That stinks. But if one wheel is dog tracking then it’s likely bent.
Good news is not too expensive and maybe you can upgrade the axle if it’s maxed out.

The No Bo 19.5 has full sized tires, and a curb weight of around 3500 lb + another 1300 pounds of carrying capacity, and it was NOT heavily loaded- no fresh, grey, or black water- just food and clothes for a week.

could a bent wheel affect the axle?

Anything is a possibility or guess at this time.

Looking at your model given it has a Torsion axle (no external springs) which uses a molded under pressure chuck of rubber to act as a spring. With torsion axles the axle stub is on a arm and that arm twists the rubber. So, it is possible jumping a curb, hitting a pothole or even a badly bent wheel could do some sort of damage..

Or the rubber inside the axle tube just failed for no reason..

Doesn't matter if the axle was barely adequate from the factory. Regardless, if it's damaged and affecting a tire, it needs to be replaced and/or upgraded.

I big rig trailer repair shop can bend the axle back to specs and have you on the road in short order.

Rolling over a curb at 5mph ?
That quite a impact especially if the trailer was going around a corner and with the tires side scrubbing "into" the curb.

One of the two big rig trailer repair shops I've used said they see lots of lead axle/curb side bent wheels and axles....cut tires or just outside rubber cuts on rv trailers.

A bent wheel won't bend a std leaf spring suspension axle. Jack the wheel up enough to roll it by hand. If it wobbles its bent and needs replaced....and have that tire checked internally.

OPs trailer from the manufacturers brochure says it has Torsion axles.

A bent or out of round wheel has the potential to cause considerable stress to a torsion axle at high rates of speed from excess bouncing. But I sort of doubt it was the main cause of the axle damage but may have been a contributing factor..

I seriously doubt any repair shop whether it is a big rig or small mom and pop can fix a torsion axle once the rubber has been damaged which is highly likely what gave out since the rubber in a torsion axle is the weakest link.

Op mentioned it is a single axle so "scrubbing" as you would know from dual or multiple axles does not happen..

I suspect that the axle the OP may be a 3500 lb rated axle, OP should be able to determine that easily by counting the lug bolts holding the wheel on..

5 lugs/bolts will typically be a 3,500 lb axle.

6 lugs/bolts will typically be a 5,000 lb axle..

One would hope that the manufacturer put a 5,000 lb axle under there..

I suspect the OP has 5 bolt rim and that would mean it would be very easy to overload that single axle in a hurry since the manufacturer claims the dry weight is just a couple of pounds below 3,500..

If it is a 3,500 lb axle and with a trailer GVWR rating of just under 5,000 lbs that means all but a couple of cargo pounds must be bore by the hitch in order to not overload the trailer axle..
