Chhh.... chhhh..... chhh noise

Interesting noise from my truck that is very random. Sporadic at best. There have been times it happens more than others but hasn't happened in some time.


I will be driving along an here this "chhhh" or "ceehhh" noise. Seems to be A/C related but cannot tell. Will load a sound when I have a chance. Thoughts?

I have the same thing, so does my buddy's F150, and civic. I don't think it's bad but I am curious to know what it is! Sounds kinda like an actuator closing or opening the vents maybe?

 

Where does it sound like it is coming from (location on the truck)?

 

Middle, front, behind dash/under hood

 

Almost feels like the truck lurches when it happens but faintly

 

Hey man! Any luck with your concern? I'm experiencing what I feel is the exact same issue. I've narrowed it down to the carrier bearing but have yet to replace it to see if that resolves the issue. Biggest concern is that it's so random. Seemed to happen more on really cold days.

 

Where is your carrier bearing? Very very random. I will say when I kick on my ac after it being off for days upon days it usually makes the screech type noise. Here is the recorded noise... Sorry it's kind of faint and windy cause of the ac.

 

anyone know how to add sound?
