So I have truck that falls within the dates for this. Clunking is very clearly coming from the rear shocks. Took it to the dealer. They heard it and confirmed it was coming from the rear shocks. They then compared it to another 22. It made the same noise so they told me it was normal. I told them if two trucks fall within the SSM window you can’t compare them for likeness. That got nowhere. Kind of frustrated with this dealer, but they are better than the others in the area. Had a vent register that was missing parts. They didn’t fully reinstall the trim around it. Not hard to snap back in, but still… also had the wiper motor recall. One wiper ended up being put back on at a much different angle. Little things, but still have pride in your work.
A couple of thoughts on how Ford could have gotten to this place that would explain it being seemingly universal:
1. Bypass shocks have been known to make noise. The engineers behind the suspension may have viewed this as a thing that would be expected. It would be interesting to hear their take on this. I’m an ME so if that was their intention I’d find the whole situation less annoying because that’s a path I’ve gone down. Unfortunately that means I know this becomes a grey area because the intended functionality would have included the noise. If the shocks don’t clunk anymore it would also be interesting to know why. There’s no guarantee something hasn’t been dumbed down to get the noise to stop. If they don’t clunk anymore and are identical in performance then why not do it that way in the first place? We all would love a bypass that’s entirely quiet.
2. Fox messed up the programming for some part in the valving and didn’t catch it for a year. I would find this odd because you always should verify that the part made by a production program is functional and new generations are a slow process. If this were to be the case, any truck in they window should have the correct part installed no questions asked.
At any rate, I would bet money that just about every truck in the SSM date range clunks.
I would love to take a clunking shock and tear it apart to compare to one that doesn’t, but that would be expensive just to learn something. If I were to ever figure it out and it was a machined part, I have the means to make these sorts of things super easy so it would be a fun project.
