Hi Damir!
Sorry to see you’ve had trouble with your axle.
Looks like your style is the mono arm type where the spindle and arm are one piece.
If I may make a suggestion……. Nothing lasts forever, especially trailer stuff.
You might want to consider the vintage of your trailer and it’s torsion axle and figure out a way for you to safely and throughly inspect it from one side to the other. You may find there are other latent issues that will need to be addressed such as mounting bolts and the axle itself.
From my own experiences over time I’d suggest that if the actual axle is sound that you plan on replacing the spindle arms, hubs, bearings and seals for BOTH sides. I suspect that if you were to take apart the other side wheel assembly, clean and inspect it you will probably find it has issues as well. Your gonna need a new hub/bearing assembly on you currently failed side anyway so you might be best to bite the bullet and get the other side rebuilt at the same time.
As this is going to be a bit of work to accomplish and depending on your circumstances and time availability might I make the suggestion to replace the entire axle & hubs assembly with a new one? You may find it’s a lot less time consuming, less hassle, simpler and overall cost effective as well. There are several on-line trailer supply houses that provide good reasonably priced replacement assemblies. That would reset the clock as it were and give you peace of mind into the future.
In our own relatively recent experience a couple of years ago with a bearing failure on our dual axle trailer this was the case and was well worth it. The difference in cost to replace the hub assembly and spindle on just one side, the bearings/seals on the other vs. replacing the entire axle/hub assembly was only about 50% more and took about the same amount (or less) of time. Serendipitously, We also found one of the U-bolts holding the axle to frame had a crack in the thread form that we would not have found had we not been replacing the assembly. So even better.
Of course these are only suggestions and your situation, circumstances and decisions are unique to you.
Best Regards,
Over Easy
