I reported my actuator failure to my parts guy at Ford, advised him numerous folks on forum had reported same, so he ordered me a different part
Note the larger gear pops off to reveal same gear as original fittment
This part is more robust than original, not exactly same, but it fits. Had to rotate shutter 90 degrees counterclockwise to gain original mounting location with gear engaged.
Works fine so far, no more clicking.
Now for bad news. Although only four fasteners, 2 10mm nuts and two T20 screws, the air bag nuts are on longish studs, deep socket removes right hand one, but left hand one (behind brake switch) may be the single most miserable fastener I have ever removed. Finally got it with 1/4 inch drive socket and 3" wobble extension.
Then the two T20 screws, ultracheap fasteners with shallow heads and braille removal, painfully slow to remove and replace.
If you have large hands, bad left elbow, bad lower back, or failed contortionist class: any one of these, have dealer do it. All of them, you can do it in 4 hours with lots of pain delays and cursing. My hat is off to BG, anyone who can do this little job in less than 1 hour has great tools and skill. I would rather remove two new turbo heat shields than do this one again.
