02 chevy,

somthing loose feels like the drivers side. i feel it in the steering wheel just turning around in the door yard.

 

The good ole chevy steering clunk?

 

i guess i dunno... how do i tell?

somthing to be concerned about?
i think i recall my mother in laws chevy truck doing something similar. but the mechanic said not to worry about it and it was common on these newer chevys

 

Oh yea, Im sure it is.. about 85% of all full size chevys have this happen.. you can pull the telescoping shaft apart and pack it FULL of grease.. that will help for a while.. But there should be a TSB about it.

 

TSB?

 

Technical Service Bulletin..

Just a fancy word for something that is wrong, but not bad enough for a recall..

All Automakers have them

 

great, so how worried should i be?
any idea how much for parts?

 

There is a bulletin on it, you can get it fixed but you it will happen again. My truck has not done it but all of my previous trucks have. It is not a big concern, more annoying then anything.

Steering - Steering Column Clunk Felt/Heard on Turns
Bulletin No.: 06-02-35-010
Date: May 09, 2006
TECHNICAL Subject:
Clunk Felt/Noise Heard From Steering Column, Steering Gear and/or Front of Vehicle During Maneuver and/or Steering Wheel Rotation (Replace Intermediate Shaft)

Attention: This bulletin ONLY applies to the above listed vehicles. All other cars with a similar condition should refer to Corporate Bulletin Number 01-02-32-001G.
Condition:
Some customers may comment on a clunk type noise coming from the front of the vehicle while driving during a turning maneuver. This condition may also be felt through the steering wheel when the vehicle is stationary and the wheel is rotated from steering stop to steering stop. Some vehicles may only exhibit the noise once for every 360°of wheel rotation. On all other vehicles, this clunk noise will be noticed during low speed acceleration or deceleration, typically in light turns of the steering wheel.
Cause:
This condition may be caused by inadequate lubrication of the steering intermediate shaft which results in a slip stick condition possibly resulting in the clunk noise.
Diagnostic Tip
Important: This condition is commonly misdiagnosed as originating in the steering gear and has resulted in the replacement of numerous steering gears without correcting the concern.
Engineering Investigation shows that numerous steering gears have been misdiagnosed and replaced. The investigations shows that if the technician incorrectly diagnoses the steering gear as the cause of the noise and/or clunk during replacement of the steering gear, the technician may stroke and/or cycle the I-shaft, distributing the original grease in the I-shaft. This distribution of the original I-shaft grease temporarily may eliminate the I-shaft clunk so that the technician believes the noise and/or clunk is corrected with the steering gear replacement and returns the vehicle to the customer. After the customer drives the vehicles for several miles and dissipates the original grease, the noise may return.
Attempt to duplicate the customer's concern and isolate the I-shaft by following the procedure below:
1. Locate a large area (parking lot) where the vehicle can be turned in a tight circle.
2. Turn the steering wheel to the right and/or left all the way to the steering lock, then off the steering lock a 1/4 turn.
3. Drive the vehicle approximately 5 km/h (3 mph) in a circle, preferably over rough pavement or seams on the road surface.
4. If a clunk is felt in the steering wheel, the MOST likely cause is the I-shaft - not the steering gear. Continue with the correction.
Correction
Important: The replacement steering intermediate shaft is physically different in appearance than the original. However, the vehicle's ride performance will not be affected.
Replace the original concentric style steering shaft with P/N 26068295, a Double "D" design. Refer to Intermediate Steering Shaft Replacement in SI.

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.

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.

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



For 2002 and later 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, 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.





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.
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.

Replace the upper intermediate shaft.
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, 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).

14.3. Reposition the carpet into place.
