So much for that escape route.

Endlinks, sway bar bushings, and subframe bolts/bushings are next on my list.

Regardless, I'm just grasping at straws here in an effort to put an end to this madness. I'm literally going insane trying to eliminate this issue.

Considering how many parts you've replaced in the process, I'm very suspicious now that any of these credit card "shim" claims were valid.

Well, I've replaced everything above the knuckle. Noise is identical. The fact that it reoccurs in warmer ambient temperatures points to something rubber/plastic softening with rising temperatures. I've also found a TON of threads on Mazda forums pointing to sway bar bushing replacement solving clunk issues.

A big bonus is that testing the endlinks and sway bushings is free, and only costs me my time.

I have also noticed that the noise is minimized or even disappears after washing the car and in wet driving conditions; I do give the car a thorough spraying underneath that should get the sway bushings wet, which could be damp the noise temporarily as the water lubricates the bushings.

It's just a theory, but I'll give it a shot. Sway bushings and/or endlinks are cheap, and not *that* hard to change.

One thing that troubles me is that it makes no sense that the noise improves temporarily after a strut bearing/mount change.

Maybe when you change the strut bearing mount change requires the lower arm to full down, recentering the sway bar in the bushings, if it does move a little, that could be the problem.

On a more serious note, though: Has anyone checked to see if their subframe bolts are tight? It's just about the only thing I haven't checked or replaced, aside from the endlinks.
Try disconnecting the end links for a short time to see if the sway bar has anything to do with the noise.
All that work to only have the noise return is a major downer.
This was one of the reasons why I got rid of mine. The other 2 were poor heat output in the winter and the DCT issues. I could have lived with the MFT issues.
Ford corporate must think the bad publicity is less costly than a recall.
I've got news for them. Bad news travels quickly in today's day and age.

Aye, I'm going to be disconnecting the endlinks tonight and taking a quick test drive.

Fingers crossed.

Here's some things worth noting:

I've encountering this noise issue at low speeds; through parking lots and while driving through the neighborhood.

I notice it whilst turning at low speeds; either direction.

It manifests at temps above 60F.


I'm starting to think this isn't a vertical coupling issue but rather a lateral, steering torque phenomenon. Something to do with the electric steering mechanism perhaps? Steering linkage?
Or maybe it is something entirely different and something to do with the sophisticated dual-clutch arrangement.

I thought it might be brake caliper related but I've confidently ruled that out as applying the brakes when it happens doesn't' change the behavior.

One thing I am confident about, the CSR Focus Fanatics dance has gone awfully quiet. It's clear they want individual owners to deal directly with dealership service departments. Ford corporate would have engaged Zillon at a more serious level if they really wanted to. Doesn't take much. What you've witnessed here is basic CS coordination - nothing more - many companies have social media positions to show "good faith" involvement in response to channels of poor feedback. That function as a "value add" is questionable. In principal it's really no different than picking up the phone and getting a CS agent. Again, this is one of those highly subjective "rattles & fitment" warranty issues. I implore everyone to engage a dealership within the first 12 months of ownership if they detect this happening to their vehicle. By doing so it get's it registered as a serious complaint.

Just to add, mine occurs when going straight.

Loading the suspension in a bumpy turn actually improves the noise.
