Wondering if anyone else has had this failure on their 1710:
You can see from the picture that the cracks propagated from the spline roots.
I mostly use the tractor with the loader so there's a little more load on the steering shaft than with no loader. It looks like the replacement part from NH is NLA so I had to try to fix it. After machining a vee, I TIG welded multiple passes (cooling the bearing surfaces between passes to keep them case hardened), then machined back to net shape. It's holding up so far.
