Yukon running board

2012 yukon, passenger power running board. Doesn’t move unless assisted. When not moving it sounds like dying seal. Probably too little too late, but I have repeatedly hosed down with pb blaster. No change. I now have the entire assembly out and am having difficulty removing the motor. Three allen bolts are out. Wedge bolt out, but wedge still in. Wedge doesn’t seem to be making contact with anything yet.

Any help would be greatly appreciated. Thank you

There should be a youtube video about the process or ask a Yukon forum about it.
