Dodge RAM 3500 4x4: I have a loud whine coming out of the exhaust

Customer Question

I have a loud whine coming out of the exhaust pipe on my 08 Ram 3500 6.7 cummins. Mostly when it is cold. Sounds like a bearing whine. Just started 3 days ago. 133,000 kms. I had the exhaust and chip done in Aug of this year.

I'm a 15 Yr Dodge dealership Cummins technician and I will need to ask a few questions before I can suggest a repair. The noise you hear could be turbo. Does the noise go away when hot? If you power brake can you hear the noise? Is there any codes in the ECM?

Post results,
Brad

It seems to go away when it's hot. I noticed my engine brake comes on a lot. I don't have it in tow mode. I can not really hear it in the cab when I'm driving. I really don't know about the codes;

Hi,

The exhaust brake should only engage when you have the button pressed in the dash.. Besides the noise, have you felt any driveability issues?

If I am going around 40 mph and let up on the fuel pedal the exhaust brake seems to kick in. The tow button is not in. I have not noticed any other driving problems. I thought when I had the work done with the mini max setup change exhaust system and chip. 3200 dollars worth. I wanted better mileage which has happened. It also sounds like a siren coming from the transmission when starting out.

Hi,

What do you have the programmer at when it sounds loud? Is it the Hot setting?

Customer: replied 4 years ago.

I just went out and started the truck up and there was no sound for maybe 5or 6 seconds and then the sound. The pyro on the on the mini max was bouncing around at between 250 and264.



All the gauges are normal and the heat is normal everyware.
