I wonder what happens when the lube eventually gets depleted and thinned out, does the clunking/rattle come back? Iíll post if anything changes. Perhaps itís pointing in a right direction. Is there a design flaw with jounce and bumper design or their interface? Can the bumper be loose from its base? Is there a problem with the materials used?

If anyone has access to these noisy pulled parts, could they examine the jounce bumpers and related parts to see if anything looks at amiss? I assume the Ford Engineers are following all the documentation/invoices and getting to the bottom of this?
I didn't want to bust your hopes of a clunk-free car, but in the past x number of months there have been a few people that came on and claimed the noise was gone after lube, just to be back a few weeks later saying the noise returned.

I honestly hope your noise stays gone, but I'm still putting my money on the bearings (which, coincidentally for me, should be in tomorrow).
