Hi Tom and Colleen,
I have had a similar problem with our 74 Winnipeg Boler that we got last year. The axle rides up at about 45 degrees no matter whether there is a tire on it or not. I decided to get a new one and have been researching it for several months.
The good news: our old axle came off fairly easily because it was held on by the 4 bolts that it originally came with, which were not badly rusted.
The less good news: I thought we would try Standen's in Edmonton (where we live), since Standen's used to make Boler axles back in the day. I phoned them up and they knew what I wanted. I took my old axle in for use as a model (one person can carry it fairly easily) and they built me a new one from Flexride components, for $375 including taxes. I kept the leading arm configuration so that I could just bolt it back on instead of having it welded, which I cannot do at home.
Unfortunately, when I got the new axle home, it did not fit. The Flexride torsion bar is too wide compared to the original torsion bar, and so it hits against the frame where the floor of the trailer drops down, which meant that the mounting holes were off by a half inch. Also, the leading arms were too short, which meant that the wheel would have been rubbing against the back wheel well instead of rolling in the centre. Not ideal.
So, I took the axle back to Standen's who told me they could only assemble pre-made components and so could not adjust the axle to fit. They refunded my money, somewhat reluctantly, and I was left with the original axle again.
What to do? the better news:
So, I gave Paul Neumeister a call in Ontario. He is having new Boler axles custom built by Dexter to his specifications, including the leading arm. After I showed him pictures by email and we talked for a while and took some measurements, he felt that his axle should fit my Boler (which is a completely normal Boler with no frame modifications whatsoever). His price, including shipping from Ontario, was only a bit more than my original Standen's price. However, I am confident it will fit, which makes it a much better deal.
I have not yet got the axle, should get it in a week or so. However, from my research it appears that Paul is the only place in Canada to get a completely stock new Boler axle so that you don't have to do any welding. His website is at

Hope that helps.
