Otherwise you'd totally miss the fact that I have managed to fix the clunk myself, and I also documented my entire procedure and parts list (all Ford parts, too). I would hope Ford would consider that to be useful feedback.
Zillon...did u simply use new but same upper mounts/bearings that comes on our cars currently...or were they part of the ST parts u purchased and therefore a diff design?

That's what I got from him... I'm sure he will chime in more!

Zillon had to replace everything from the strut up, to include the upper mounts, as the ST parts are different (but a direct bolt-in).

I don't know, I think that the problem is noticed by many, honestly. When I went to order my replacement bearings (which have conveniently been 'lost', with no verification of purchase), my parts dept. informed me that there were over 4400 bearings on back order at the time. Most people that I have seen have the issue on one side of the car, but even if you assume that a set was ordered for each car,that shows that there are over 2200 vehicles with the problem...

The ST uses the same bearings as the regular Focus (Ford #CV6Z-18198-A / Motorcraft #AD-1094). So, if my noise returns, I can directly blame it on the bearings.

The ST-specific parts that I did use were the top strut mounts (#AD-1098) and the front struts (#AST-12281 LH F strut / #AST-12287 RH F strut). Everything bolts right in without an issue. I'm also lowered on Eibach Pro-kit springs, which is why Ford wouldn't touch my car.

I also used the following torque specs, because I believe the bearing and mount are super-sensitive to being overtorqued:
Center strut nut: 50 ft-lbs
Upper mount bolts: 25 ft-lbs

I also used a prolific amount of lithium grease between the bearing and the strut mount, on the bumpstop that fits into the bearing, and around the seam of the strut bearing itself.

Ok...that's what I thought u did. You're right...if the noise returns it will probably be those bearings. I'm watching for the st's to develop the issue...and if yours returns too. (Hopefully not!). I'm sure the added grease helped.

SCREW. THAT.
I have the same rattle, and cluck at low speeds. I don't want their mechanics to be guessing what the hell is wrong, or keep trying the same TSB over and over again that does not solve the problem. Insanity = doing the same over and over again expecting different results. I may end up taking it to a dealer next weekend the noise is starting to irk me. We'll see.... Some service managers and mechanics feel they know better just because they work at the dealerships service department. To think I traded in my perfectly working 2006 Honda Accord SE, that had no front end noise for this. WTF

No not all of the cars are affected by this issue at least as far as I know. Mine doesn't sound like that passat from the Top Gear U.S. Fuel economy challenge with the blown strut clacking everywhere. For the most part its really quiet except for the road noise from the tires or the sound of the suspension compressing and rebounding over speed bumps/etc. I have to drive over several speed bumps at least 2x a day to get into and out of the apartment complex so if that was a condition that would cause the clunk to become evident I think I would have heard it by now.
