- 6.7 Cummins
Good morning, y'all. A little background: I'm running a 2017 2500 4x4 CC LWB 6.7L Cummins, 68RFE automatic with 153,000 mi.
A few weeks ago, my truck started making this weird, whining/grinding noise from somewhere under/in front of the cab. I couldn't tell from where exactly, but it was very intermittent and it would just do it randomly. It would only do it while in motion, usually between 40 and 50 mph. I couldn't replicate it. The truck would do it when it wanted to, for maybe a second or two, then quit.
I never felt any loss in power, no jerking, just noise. It gradually started getting worse, so I had a friend look at it. The sound stumped him, but he said it sounded similar to a motor pulley sticking. I had another friend, who is a mechanic at a local dealership (wish I would've thought of him first), and on a drive, he had me shift transmission gears, thinking that might be it, but no, thank God.
What we discovered is that when it did it, it quit when I shift into and immediately out of 4HI. Eventually, it started grumbling in 4HI too, so I'm getting the transfer case replaced. I also found out my t case isn't electronic shift, and there were only three available in the nation, 80+ on backorder. I guess not really looking for advise, but if anyone hears a random noise from under the truck, try that.
