Just saw your message. i would use it until it goes. Mine lasted about 100 hours. I bought a new bearing kit for it and tried to rebuilt it but I did not know at the time it was the spindle itself that was just too weak for it's job. The rebuild only lasted a few hours. I would order the new thicker spindle off ebay for around $180 and keep it to replace the other one when it goes. They cost about $240 from a dealer. Replacing the whole spindle only took about 30 minutes. I will try to look up the new spindle part number tomorrow so you can make sure its the new redesigned one.
