Cobalt L4-2.4L VIN B (2006)
Replace the intermediate shaft.
Important
If the vehicle has already had a steering intermediate shaft replaced for a similar noise concern that the dealer duplicated, determine from the
customer if the noise went away for a period of time and came back, or if the service shaft made no change. If the noise was gone for a period of
time and came back, have the dealer replace the shaft again to verify we do not have a defective service shaft.
If this does not eliminate the noise, continue to diagnose the vehicle according to the diagnostics in SI.

For vehicles repaired under warranty, use:
Condition #5
Some customers may comment on a rattle/clunk type noise coming from the steering column when driving over bumps.
Correction #5
The following steps have been found to be very effective in removing this condition.
1. Check for the possibility of the PCM and the TCM rattling/clunking together. If there is contact between these two modules, insulate the modules
from each other using a small piece of foam.
2. Check that the retaining clip on the engine coolant surge tank is fully seated. If not, push down to seat.
Rattles/clunks in this area of the engine compartment may be heard as coming from the steering column while driving.
If this does not eliminate the noise, continue to diagnose the vehicle according to the diagnostics in SI.
