Does anybody know of the quality of the steering boxes from Kumar, specifically for the kubotas? I have a hydro model b8200 and it needs a replacement or a rebuild. I have attempted to rebuild last spring. it held for a bit then came apart again and did so pretty bad this time (i think i should have went with gear oil instead of grease). i re-welded the ball nut but my confidence is low it will hold therefore i'm looking for other options. Thanks for your help.
