There is a lot of good info here on axle
You can buy a new replacement axle here.....
But I'm more interrested in Roy in TO's approach......
By the time you've read his excellent thread, you'll be an expert.
I knew this is what I wanted to do but it's nice to see it's been done, thanks Roy.
Another major issue with Bolers is poor design in a few structural spots.
One of the worst is at the forward, bottom of the door opening.
The bowed steel "frame" stops at the top of the gaucho platform and these trailers bow out at this point and seperate from the floor pan causing all sorts of grief.
Again Roy has addressed this problem as well here....
