AWD feels loud

[Illnasty]

does anyone else feel or hear that their truck is loud when it’s running in AWD? I rarely have to put the in AWD but I feel that she’s pretty loud when I’m accelerating in the mode.

Wait, auto? 4 hi?

It will be a little louder... in both, you’re basically locking the hubs in auto 4wd and in 4hi you’ve got the tc putting power to the front wheels. It shouldnt sound overly loud but it will sound a bit louder yes.

Yes. Even in the auto-4wd mode it will be quite noisy in comparison to 2wd.

Thanks all for the replies

I thought those K2s did away with AWD for 4WD?

Mine is like Pete's just a mite louder when the front axle is engaged and usually cannot even tell. It's got good bearings and a fresh fluid.

My wifes Denali has 2wd, auto 4, 4wd and 4-lo.

I only hear a slight difference, and only under hard acceleration. Same on my 2015. Auto(AWD)/4Hi/4Lo/N are options on the 2 speed transfer case for 2015-1018.

I rode in an Uber Black 2015 Suburban with 182,000 miles, no different.
