Strange sound at idle, not the tick

[Andree]

Keep hearing this at idle once it warms up or whenever o sit.

That doesn’t sound healthy.. not sure what that is.

 

[Andree]

Ya i dont know. Iv got no codes, sounds fine running, performance seems fine. Iv got nothin

 

[Ratket]

Is that a train in the back ground followed by lifter tap?

 

[Andree]

Does sound like one. Fk

 

[Andree]

Maybe water pump or some bs. Just found out the other day that my heater core has a very small leak. Cpl drops on paper towel per week.

 

[blackbeautyhemi]

Could be, water pumps do rumble like that when they’re about to go.

Stopping by dodge today after work. I hope its something like that. Someone suggested a connector rod bearing or pulley

 

[Ratket]

So that’s not a train in the back ground? All that noise it ur truck???

 

[Andree]

Lol yes. When i start it in morning it sounds fine then few seconds later when it starts warming up and calming down it makes the grumble sound. It actually sounds way louder on that clip than it really does. But i noticed going through drive thru u can hear it a bit.
Never noticed before because i always walk around back of truck in morning.

 

[Andree]

I tried again

 

[Ratket]

Take it to a dealer before it strands you some where

 

[Andree]

Already did. Took him a min to hear it. He said yep. Somethings ******. Hes 100% sure its not internal thank god. Said it sounds like one of the pulley bearings or the AC clutch and to come back in a few days.
