Date: March 26 2008

Subject:
Clunking Noise Under Hood and Can Be Felt in Steering Wheel and/or Steering Column (Replace Upper Intermediate Steering Shaft [I-Shaft] Assembly)

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

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.

Supercede:

This bulletin is being revised to add diagnostic information (refer to Diagnostic Tips) to check the lower steering column bearing as a potential source of the noise. Please discard Corporate Bulletin Number 00-02-35-003M (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.

^ The lower steering column bearing may create the same noise as the intermediate shaft. Before replacing the I-shaft, verify the noise isn't being caused by movement from the lower steering column bearing. Check the bearing for movement by pushing up and down on the I-shaft where it attaches to the steering column.

^ 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

Important: ^ I-shaft P/N 19153614 has been designed to replace previous designed dampened and non-dampened I-shafts. The physical difference in the yoke size will accommodate all vehicles listed in this bulletin.

^ Due to the design of the new I-shaft, it is not possible to lubricate/grease the I-shaft.


Replace the steering column upper intermediate shaft with an improved design shaft that will eliminate the clunk noise using the procedure listed below.

1. Set the front wheels in the straight ahead position.

Notice: On the 2002 and later model year vehicles the steering column LOCK was removed from the steering column. It is critical that the J 42640 - Steering column Anti-Rotation Pin is used when servicing steering columns on 2002 and later model year vehicles. Failure to use the J 42640 may result in damage to the SIR coil.

2. Set the steering wheel in the LOCK position on 2001 and prior model year vehicles.

3. For 2002 and later vehicles install the J 42640 in the steering column lower access hole.

4. From under the hood remove the lower bolt that connects the upper intermediate shaft to the steering gear coupling shaft.

5. Slide the shaft towards the dash in order to disengage the shaft from the steering gear coupling shaft.



1. From inside the vehicle slide the shaft down and off the steering column.

2. From inside the vehicle slide the upper intermediate shaft through the dash boot seal and remove the shaft from the vehicle.


9. Replace the upper intermediate shaft.

10. Install the upper intermediate steering shaft through the dash boot seal and slide the lower end into the steering gear coupling shaft.

11. Raise the upper end of the intermediate steering shaft and install into the steering column shaft.

12. Install the upper bolt and nut.

Tighten

Tighten the bolt to 47 N.m (35 lb ft).

13. Install the lower bolt and nut.

Tighten

Tighten the bolt to 50 N.m (37 lb ft).

I tried to install the upper I-Shaft (P/N 19153614) purchased from www.partswebsite.com/simongmparts onto my 2004 Silverado 1500 4x4 and the new part is too big and wont fit into the steering gear coupling shaft?? I had to reinstall the old I-Shaft. Is this normal ?? I don't want to grind it in order to make it fit should I ask for a replacement?
