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 update the repair procedure with a permanent fix. Please discard Corporate Bulletin Number 00-02-35-003L (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

Replace the I-Shaft with P/N 19153614.

Do NOT lubricate or exercise the I-Shaft.

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.

<LI type=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.

<LI type=1>Set the steering wheel in the LOCK position on 2001 and prior model year vehicles.

<LI type=1>For 2002 and later vehicles, install the J 42640 in the steering column lower access hole.

<LI type=1>From under the hood, remove the lower bolt that connects the upper intermediate shaft to the steering gear coupling shaft. <LI type=1>Slide the shaft towards the dash in order to disengage the shaft from the steering gear coupling shaft. <LI type=1>For vehicles equipped with adjustable foot pedals, perform the following steps:

6.1. Reposition the carpet away from the accelerator pedal position (APP) sensor.

6.2. Remove the two nuts retaining the accelerator pedal to the bulkhead.

6.3. Reposition the accelerator pedal out of the way so the intermediate shaft can be removed.

<LI type=1>From inside the vehicle, remove the upper bolt from the upper intermediate steering shaft (1) to the steering column connection. <LI type=1>Remove the upper intermediate steering shaft assembly.

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

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

<LI type=1>Replace the upper intermediate shaft. <LI type=1>Install the upper intermediate steering shaft through the dash boot seal and slide the lower end into the steering gear coupling shaft. <LI type=1>Raise the upper end of the intermediate steering shaft and install into the steering column shaft. <LI type=1>Install the upper bolt and nut. Tighten
Tighten the bolt to 47 N·m (35 lb ft).

<LI type=1>Install the lower bolt and nut. Tighten
Tighten the bolt to 50 N·m (37 lb ft).

For vehicles equipped with adjustable foot pedals, perform the following steps:

14.1. Reposition the accelerator pedals into position on the bulkhead.

14.2. Install the two retaining nuts.

Tighten
Tighten the nuts to 20 N·m (15 lb ft).

Thanks for the help. I have the newest shaft already. As far the bearing, i tried the hose clamp method to see if it was the bearing and it still made the noise. Its noticable going around 25 to 40 mph. The bumpier the road, the worse it is. I'm at a loss here. I think i may end up callinh the dealer tomorrow. It made the noise ever since I bought the truck but I always thought it was it was the ISS. But i have the new one and the noise still persists, and seems like its gotten louder. The dealer even told me it was probably just the ISS when I bought it. I'm hoping they can give me some sort of a discount if they fix it seeing it was never right upon buying the vehicle and I was told it would be fixed. What do you guys think? Thanks
