#1 of 8 grinding noise when driving '04 tahoe by andrew1968 Feb 14, 2007 (1:33 pm)
I have an 04 tahoe with 52,000 on it. it has full time 4wd that cannot be turned off. my question is when i am driving and barely pushing on the gas i hear a grinding noise. it sounds like a brake pad needs replaced but its not that I checked all four corners. when i let off and coast it goes away. from what I can tell it is comming from the left front. it is not a constant grind but almost like half of a tire revolution grinds and the other half is fine. also please tell me how to fix the steering shft chatter. thank you Replies to this message: beach15 (Feb 14, 2007 8:02 pm) andrew1968 (Feb 15, 2007 2:32 pm)

Replying to: andrew1968 (Feb 14, 2007 1:33 pm) 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.

Please discard Corporate Bulletin Number 00-02-35-003K (Section 02 -- Steering).   --------------------------------------------------------------------------------- -   Condition 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.   Diagnostic Tips 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.   Correction DO THIS DON'T DO THIS   Fully Exercise/Stroke I-Shaft 5-6 times DO NOT REPLACE the following intermediate shaft P/N's:   P/N 88965505   P/N 89060582   P/N 19149105   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.

Replying to: beach15 (Feb 14, 2007 8:02 pm) 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 8 04 4WD system by rs1807 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 8 04 4WD system info by rs1807 Mar 12, 2007 (10:49 pm)
"Transfer case, electronic Autotrac, includes push-button controls 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 8 More info by rs1807 Mar 12, 2007 (10:58 pm)
FULL-TIME 4WD   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 8 2004 Chevy Tahoe Z71 by johnny4016 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?
