Power Running Boards - 07 and Later


I need some help with the power running boards on my 09 Navigator. I have found a ton of info on the pre 07 running board issues (which were a different design) but very little on hte 07 and later. The driver side running board started making a god awful noise and not really moving up or down. I just got around to removing it the entire running board today because I couldn't figure out how to remove just the motor.

Is there a procedure hiding out there on how to remove the motor from the running board assembly?

And why in the world are these motors $650 or more?
