Could be a number of driveline things, but a bigger question--why do you think your 4wd can't be turned off? There wasn't a single '00-06 Tahoe equipped like that, as all 4wd models got 2Hi, 4Hi, 4Lo as choices to run in via push button. So it's a bit odd why you said that.
Regardless, it could be a bearing, maybe, though I'm not sure why it might come and go with gas/coasting.
As for the steering shaft, the latest procedure from GM is to disconnect the lower end and stroke it in and out to distribute the grease inside--compared to manually lubing them, or replacing them. It's another temporary fix, but that's the latest directions from GM to dealers. Here's more on it:
Subject: Clunking Noise Under Hood and Can Be Felt in Steering Wheel and/or Steering Column (Exercise/Stroke Intermediate Steering Shaft Assembly) #00-02-35-003L - (11/29/2006)
Models: 2002-2006 Cadillac Escalade Models
1999-2007 Chevrolet Silverado Models (Classic)
2000-2006 Chevrolet Suburban, Tahoe Models
2002-2006 Chevrolet Avalanche
1999-2007 GMC Sierra Models (Classic)
2000-2006 GMC Yukon, Yukon XL Models
2003-2006 HUMMER H2
Attention: This Service Bulletin DOES NOT include Mid-Size Utilities such as Buick Rainier, Chevrolet TrailBlazer Models, GMC Envoy Models or Oldsmobile Bravada. Refer to Service Bulletin 02-02-35-006A or newer for Mid-Size Utilities.
This bulletin is being revised to change the service procedure. Please discard Corporate Bulletin Number 00-02-35-003K (Section 02 -- Steering).
Some customers may comment on a clunk-type noise coming from under the hood that also can be felt in the steering wheel. These conditions may be more noticeable when turning at low speeds on rough road surfaces.
Use the information below to help diagnose the source of the noise.
• Frame Snap and/or Popping Type Noise -- A frame snap or popping type noise can be duplicated on rough or smooth road surfaces with steering wheel input to the left or the right. This type of noise can be HEARD and is typically louder with the windows rolled down. For additional information, refer to Corporate Bulletin Number 03-08-61-002F or newer -- Snap/Popping Type Noise Coming from Front of Vehicle (Remove Front Crossmember, Change Fastener Orientation)
• Intermediate Shaft Clunk -- Intermediate shaft clunk is heard and FELT in the steering wheel and/or steering column area, typically while driving on rough road surfaces with steering wheel input.
DON'T DO THIS
Fully Exercise/Stroke I-Shaft 5-6 times
DO NOT REPLACE the following intermediate shaft P/N's:
DO NOT LUBRICATE the Intermediate Shaft (P/N 26098419)
Engineering has determined that fully exercising/stroking the I-Shaft will provide similar results as lubricating.
Disconnect the I-Shaft underhood.
Fully exercise/stroke the I-shaft a minimum of 5-6 times.
Reconnect the I-shaft.

Thank you for the repair advice on the steering noise. Also with all do respect my tahoe's 4wd cannot be turned off it is all-wheel drive with sabilitrack. there is no option on the instument panel to turn it off. it only has all-wheel drive,4lo,or Stabilitrack. if i could get it turned off i would have a lot more fun in all this snow we just got.thank you

I have to agree with andrew1968 I also own the 04 tahoe LT ...the fraking stupid thing will only do all-wheel drive,4lo,or Stabilitrack . ALso andrew1968 you can actually turn off the stabilitrack according to the manual u do this to transfer more power from the engine to be able to get out of a stuck in the snow situation ..you press it and on ur dash it will say disabled ... hehehehehe.....
#5 of 21 04 4WD system
Mar 12, 2007 (9:58 pm)
I'm looking at a 2004 Tahoe with the same AWD system as in Andrew1968's. I'm looking for some information about it. Is it a different transfer case design like the Denali's, but with buttons for 4low?
I also noticed the slight vibration when turning or taking off at low speeds but then it seems to go away.
#6 of 21 04 4WD system info

"Transfer case, electronic Autotrac, includes push-button
1 - Requires 4WD models. - Not available with (JL4)
StabiliTrak, vehicle stability enhancement system. (NP8)
Transfer case, open differential, 2-speed
1 - Included and only available with (JL4) StabiliTrak,
vehicle stability enhancement system. (NR4)"
It looks like you had to have AWD for stabilitrak to work. You also couldn't have a locking rear diff with stabilitrak.
#7 of 21 More info

A second version of a 4WD transfer case is a full-time 4WD transfer case. This style of transfer case has an open center differential to allow for different speeds between the front and rear axles and operates similar to an AWD system. This transfer case can be locked to operate like a Part-Time 4WD transfer case (no difference between front and rear prop-shaft speeds) and/or uses a traction control system to assist in low traction situations. These transfer cases also have a selectable low range. An example of this type of 4WD is the H2. RPO code is NR4.
#8 of 21 2004 Chevy Tahoe Z71
Mar 13, 2007 (7:19 pm)
I own a 04 Tahoe Z71. It has the push buttons on the left side of the steering wheel for AWD, 2 Wh, 4Hi, and 4Lo.
What yours has might be different than mine.
Most AWD vehicles mean that it is in 2 wheel drive when driving on normal dry pavement, when it feels a slippage it shifts the transfer case into AWD.
On my 2004 Tahoe I can shift from 2Hi to 4Hi while moving. But I have to be stopped and in nuetral to shift into 4Lo.
I hope that this helped?

What was the solution? I have an 04 full time AWD and aloso experieice a grinding noise when under power, which also disappears when letting off the gas.
#10 of 21 05 Tahoe 4wd transfer case replacement
Feb 05, 2009 (8:58 pm)
I have a 05 Tahoe Z71 w/ 70k miles. I just found out that the transfer case needs to be replaced. Is this Common or are their any recalls? I was told it will cost me $2100
#11 of 21 2004 Chevrolet Suburban Transmission Problems
Feb 09, 2009 (8:41 pm)
I have 48,000 on my '04 Suburban, today while driving it just all of a sudden made grinding/fluttering sound and then fell out of gear. The engine revs fine and there is no fluid leaking anywhere. I worked it through all the gears but it would not move forward. I had to have it towed. Any opinions on what might be the cause of this?
