Hi all, I noticed a buzzing sound the other day but it went away.. today after doing oil and fuel filters charges I was able to hear it more clearly. Buzzing happens only when car is in park with foot on brake. What could this be?
2020 ram 2500 diesel 6.7
54k miles

Let me know your thoughts and if anyone else is hearing this too

You can't "load" videos to the site, only "upload" allowed is images.

Put it on a media site and use the insert media option to provide a link.

So when you step on the brake that’s the change in sound?

Correct.. when truck is in park and you press on the brake is when you can hear it.
Doesn't seem to happen when truck is in drive

If thats the case it could be something with the powersteering or hydro boost. Would be best to poke around with a stethoscope
 
That’s not lifters. That’s hydroboost.
 
Fairly normal for the power steering pump/hydroboost. You’re not at the OEM service interval, but it couldn’t hurt to use a turkey baster to empty the PS pump reservoir and add new ATF+4.

I do that every oil change.
