TSB for steering clunk

[Red 'rado]

My 03 2wd ust developed the steering clunk at 9000 miles. I know a ton has been posted on this topic and I searched through the information but I did not see a link to the TSB about replacing the intermediate steering shaft.

 

Can anyone email it to me or post it here so I can print it out? Are the dealers replacing the intermediate shaft on the 03s or are they just lubing them up? I would like to get it fixed right the first time and don't want to get the run around from the dealer.

The dealer knows about the problem. The shafts are on Backorder for 6 weeeks. It is a known problem. Take the truck to the dealer and if the shaft is the problem they will put you in line with everyone else to get it replaced. I just went thru the same thing and I am waiting for a call from the dealer when shafts get in stock.

This Service Bulletin DOES NOT include Mid-Size Utilities such as Buick Rainier, Chevrolet TrailBlazer / TrailBlazer EXT, GMC Envoy / Envoy XL / Envoy XUV or Oldsmobile Bravada. Refer to Service Bulletin 02-02-35-006A for Mid-Size Utilities.

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.

 

Correction

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

 

Set the front wheels in the straight-ahead position.

 

Notice

On 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 these steering columns. Failure to use the J 42640 may result in damage to the SIR coil.

 

 

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

 

 

 

Install the J 42640 in the steering column lower access hole.

 

 

 

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

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

For vehicles equipped with adjustable foot pedals, do the following steps.

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

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

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

 

 

 

 

From inside the vehicle, remove the upper bolt from the upper intermediate steering shaft (1) to the steering column connection.

Remove the upper intermediate steering shaft assembly.

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

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

Replace the upper intermediate shaft. See the parts table below.

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

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

Install the upper bolt and nut. Tighten

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

 

Install the lower bolt and nut. Tighten

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

 

For vehicles equipped with adjustable foot pedals, do the following steps.

Reposition the accelerator pedals into position on the bulkhead.

Install the two retaining nuts. Tighten

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

 

Reposition the carpet back into place.

Thank you both for the replys. That is what I am looking for.

Does anyone know what this J 42640 pin is and more importantly if you can make a makeshift one? Also where is the steering column lower access hole?

 

Thanks!

Can someone describe this condition, I think my truck may have this. Here is what I am feeling. On mine I feel every bump in the road through the steering wheel especially when going around corners, kind like the shaft is loose or has some play in it. It doesn't really clunk, maybe more like a tap. May just be in the begining stages. I'll see if it gets worse over time. BTW 2002 GMC Sierra Z71 about 27K miles
