Pulley/belt squeak

Call ford and start a case

So I went in and started it with the service manager and pointed out the noise. Kind of brutal that’s how it has to go but at least now we’re on the same page that something isn’t right. They’ve been poking around most of the day and believe they have the sound isolated to the tensioner assembly which they will replace tomorrow. I’ll report back after that.

Awesome! Keep us posted. Not sure my truck has even been looked at yet, been there since tues. In Los Angeles.

Small update on my end. Spoke to service advisor, they were able to reproduce the noise. They have not isolated it to a specific area or part yet. They did mention there is another raptor r in with a similar noise that is coming from supercharger and is misfiring and has low oil pressure.

Yuck that sounds like a ****** situation. I got my truck back this morning, several of the drive belts were worn/glazed so they were replaced with the tensioner belt and pulley. They say this got rid of the noise but I won’t know for sure until I can test it in conditions where I had the noise before. I’m letting it sit at work so I’ll update again when I leave later and can do a cold start.

Hopefully you get some good news about yours soon!

Are they saying they believe the chirping sound is associated to the supercharger and low oil pressure? Or that particular raptor is in for multiple unrelated issues?

That particular raptor r is in for multiple issues but the noise it has is similar to mine apparently.

I’m on my second 24 R. The first one did not make the chirp, the one I have now does chirp for a few minutes after cold start. I get a loud crackle during cold start as well, and more burble/pops when decelerating than my previous 24 R.

I’m also convinced it’s not making the same power. Could be in my head, but it just doesn’t feel the same. I hear zero supercharger. There’s also a metal ticking noise that increases under load/acceleration over 3k rpm. I don’t know if the exhaust is loose, or there’s a baffle loose, I’m not sure.

@ToadSmasher2K1
First one sounds normal to me; my exhaust sounds the same. The exhaust rattle is common prob with other raptors that have adjustable baffle.
Second one sounds like the chirp.

Mine also has that exhaust sound on start up, and I get a lot of pop/burble on decel too but coming from years of turbo sports cars I consider that a plus haha.

Like 310 said, the second video sounds exactly like the chirp I have. I did start my truck after 4.5 hours out in the cold, and had no noise so that’s encouraging. I’ll wait for the first start of the day tomorrow to call this fully resolved, but I think it’s looking pretty good.

Edit: Forgot to mention that I also hear next to no SC whine unless I’m completely burying the pedal, haven’t done much of that yet.
