Yep, that's how 3rd gen spindles fail every time, the bolt rips out around the weld. 5/8" is way more than strong enough (Go with Grade 8), don't spend any extra money or headache on larger or more complicated axle setups. 5/8" is overkill and well proven on the Yerf, any larger is a waste. The problem with the stock setup is how Yerf Dog welded the bolt to the outside of the spindle body. If you look at it, it's the spindle body that fails, not the bolt itself.
The fix is running the bolt through both sides of the spindle body, and welding on the back side. Seems like ancient history now, but we've been doing this since the days of the GX150 Yahoo Group back in 2004/2005. Here are my latest HD spindles as an example. Wanted to showcase the through-bolt setup in this version as a callback to that history, so I worked out a beefy open-body design so you can see the bolt running through.
I've got the weld-on reinforcement plates separate if you want to DIY fix/retrofit your originals. You'll be ready for front brakes as well.

It was loads of fun until..
I'm debating going away from 5/8" axles. Would really like tapered trailer type. Need to do some research.. |
