Apparently all of these vehicles have the issue:

What is "pump rub"
The GM transfer cases use a gear pump inside the case that is driven off the mainshaft. The pump forces oil to the planetary as well as the drive sprocket sleeve. Because the pump is driven by the shaft, the housing of the pump must 'float' in the rear housing. There are 5 tabs around the housing that fit into spots in the rear housing to position the pump. Over time, the pump can start to wear on the rear housing. GM installed a spring steel clip in the housing intended to prevent wear but the clip can break and render useless

Being that the pump housing is aluminum and is a harder material then the magnesium rear housing, it can wear a hole in the rear housing and cause a very small leak. This leak is high enough in the case that it typically will not leak when vehicle is not moving and therefor not leaving any drops on the ground. Typically the condition is not found until there is transfer case damage from running the case out of fluid.

Avoid costly repairs to your transfer case by preventing this condition.

A new truck is $55K+. The transfer case is $1500 and the truck runs great otherwise. The Duramax should last twice this mileage, so I'm told.

My truck was $69 K

It's a 2012 HD 2500 Duramax (Durajunk)

Problems

(1) Coolant sensor on block replaced 2 Times
(2) Steering column Replace @ 15 K Miles
(3) Front Driver side strut has been replaced 4 Times
(4) Back seat panel Driver front has been replaced 3 Times , still fucked up!
(5) Drivers door panel has been replaced 2 Times , Still fucked up.
(6) Switch for sunroof light burned out at 20K Miles .
(7) Trim around front windshield had to be glue to body as at 75 MPH the chrome would make noise .
(8) Back up sensors have been replaced 4 Times, Just quit working so needs to be replaced again .
(9) I know there is more things can think of them now

I think all the newer stuff GM builds is Junk !
