Bad newsLower bearing started making a noise in less than 10 hours, It has china bearings, seller reply for me to return the spindle, amazon is not allowing me the option to complete the return process.Good newsthe housing appeared to be made very good, heavy duty, it appears the weak point is cheap china bearings.The internal shaft appear to be solid, looks like 316 SS, but not sure

Bolted right up to badboy outlaw mower. Everything was just like it was listed. Hopefully it last like original. Very impressed. Price was about half what badboy was. Good deal. Would recommend.
