Is anyone else experiencing a whining noise when their truck is in 4 wheel drive? Ive had me '13 in 4 wheel drive for the first extended time due to snow. I really notice it when coasting.

i hear it too also only when coasting, i figured it was normal since mine did it before and after i did the pump upgrade and everything looked great inside. i also use Mobil1 5w/30 synthetic engine oil instead of ATF and the noise never changed.

just sounds like gear mesh noise to me.

Yup i hear it as well... I accidentally left it in 4hi once, and I heard the whine and I thought my trans was taking a dump on me... then I realized what it was. At the next red light I put it back into 2wd and it went away.

Yeah my 2016 does it. Took it to dealership and diesel mechanic said we would treat it as normal. But if it got louder or changed at all to bring it back in.

My 07 was doing it for months and would get louder with tc lock up. Then I towed a 30ft trailer from Florida to Ohio up i77. When i got to Ohio the noise increased and I found a metallic fluid coming out of the front drive shaft seal.:rolleyes:

Whining in 2wd is a much worse thing than the truck whining in 4wd.

I have the same issue. It seems like more when in 4 wheel drive and on pavement. Dealership said it’s normal but I’m still going to keep a ear on it

My 11 model was pretty quiet in 4 wheel drive but then my 17 model and now my 16 model both make a pretty good whine..
