I had this service done to my clunking '02 several times, to no avail. It became a real problem to get a dealer to believe it was something else, they all insisted this had to be it. The shaft got replaced once or twice, too. Didn't help a bit.

Finally had the steering box bearing changed. At the time there was no TSB for this procedure but people were talking about it on TDP and I managed to talk my dealer into trying it. Problem solved. It's now 40K miles later and still fixed.

Just a heads-up that there's more than one possible source for a steering column rattle.

I just started getting the clunking noise on my 03 2500HD, only 5000 miles on it, took it to the dealership today and service tech said it was the westin nurf bars somehow making the noise, too the truck home and the bars are tight,, actually had teh bars on since 200 miles and the clunking at low speed and slow turns started last week...
