Correct part, missing grease
The part works great and the step-by-step instruction video was an indispensable resource. My only issue was that the grease that was supposed to be included with this part was not initially shipped. I left a voice message that was not returned, but the missing grease was shipped immediately and with no charge when I called again a few days later.
