Grinding noise in 1st gear - 2007 Denali

[dictum]

Transmission appears to work fine but it's grinding when slowing down or taking off. The noise goes away above 10mph.
Seems like it's the AWD component that's failing?

It cannot coast, something is strongly rubbing and it slows down.

Get it on a lift at a local garage and get the wheels off the ground, and with a person in the truck, put it into gear. A mechanic with a stethoscope can walk around under the truck and pinpoint the area where the noise is coming from. Then, you can figure out what to do to eliminate the source of the noise.

Good description! I hope it’s a wheel bearing. Grinding like you’re describing should be pretty easy to find once it’s on a lift as previously recommended.

Looks like the other member is having same issue at same time.
