Part 22670 is attached to the interior-half of the handle, which is part of the door panel, The fake-Chrome Outer handle piece # 22670 attaches only by those little grabber clips, and the plastic tabs that hold the clips to part 22670 AND the interior half of the handle that is part of the entire door panel can easily break off from either part, and then you are screwed.
Remove the plastic chrome-colored slowly and carefully using two smooth butter knives, prying a little at a time until you have a separation equally across the chrome-colored handle piece. The door panel is removed by unscrewing the larger TORX screw under the handle, in the middle of the handle. There is also a door panel attachment screw hidden under the round plastic plug beneath the door pull. Then remove the (3) smaller TORX screws around the curved part of the door panel...and then CAREFULLY pry off the entire door panel using the two butter knives slowly and carefully. The door panel is secured to the door interior metal frame around the panel edge at various locations with pop-off fasteners that can be re-used by taking acre during removal.
If the black inner-half of the door handle that is part of the plastic door panel itself has broken you will have to get a replacement door panel, and I'd try a local junkyard to the tune of probably 50 bucks, or so. I don't know how much a new one from FORD would cost.
I replaced my OEM door speakers because after 6 years, the speaker cones had baked in the hot sun and lost their ability to rebound without friction and scratching noise from becoming brittle. (A new replacement front door 25W speaker is about 24 bucks each from the Dealer.)
Back door dual-cone speakers haven't failed or lost paper rebound movement, so go figure.
