Well I thought I might have an idea? But your picture does not quite show what I was looking for.
Do you have the part of the spindle that goes through the axle? Does not really matter there are alternatives.
Do a google search for PF Engineering, They sell plans for a homebuilt Loader and Backhoe.
Along with that they show a few ways to beef up the spindles to carry the load of a loader.
I'm mentioning it because as they say a picture is worth a thousand words, and will show you far more than I could describe.
In fact here is a link. In the menu on the left side near the bottom is the spindle mod section.http://www.p.f.engineering.50megs.com/
BTW that White is a GT
I've been keeping an eye out for, they are very much under apreciated and rated.
