Never heard of one breaking, been a common problem on GM pickups for 10+ years?????????? I would be interested to hear how your 07 shaft is holding up in 20K.

Instead of going through all that, go to the back of your owners manual, pick up the phone, and call GMC customer service.
Make sure you have the VIN # of your truck.

Explain to the person that answers that your truck has a bad intermediate steering shaft, go into as much or little detail as you like, and you want it replaced with the "newly engineered" 2007 shaft----One caveat the truck has to have less than 70,000 miles on it.

If you do this during your dealer's normal business hours, the customer service rep will ask for your dealers info (location/phone number)...What would be a convenient time for you, and if you will hold the line while he/she calls to make an appointment for you. The rep will also make sure the part is there for your appointment.

Dealers hate getting calls from C.S., and will bend over backwards to make sure your happy; You may also be asked to take a survey to see if everything turned out all right.

As far as I can tell these shafts were installed as early as the '98 model GM/GMC trucks, and the engineers didn't come up with a fix until 2007

I have an '03 Silverado that had three replacements (not greased) done before it ran out of warranty in late '06. In January '07 I found out about the extended warranty, and made the call, and I have been happy ever since!........Knock on wood...

Just recently, I recieved in the mail a settlement notice about Instrument panels going bad, they have been placed under the 7year/70,000 warranty.
I don't think I'll hit the milage, since I only have 32,847, but I'm good till 2010.

Hope this helps, Spread the word!

This is a huge known problem with GM .Its very easy to do it yourself.Just call your Gm dealer and ask them for this kit,Part number is GM 26098237,It comes with a thing of grease and a rubber cork like stopper with intstructions.Takes maybe a hour to do the first time.And i can tell you ,you will do it almost every year.Theres no danger of anything falling apart from this clunking shaft,its just a poor design.You can buy a after market shaft that will fix this problem.If you want to spend the money get yourself a Borgeson,they gaurentee to solve the problem

What he said.

But it can't break. It's a spline engagement and frankly will get to a certain noise level and not get any worse. The splines have too much clearance that the grease takes up. The grease gets pushed to the side and the knocking starts. At one point we were supposed to take one end of the shaft loose and work it through it's full range to redistribute the grease as an interim fix.

It did start on the '99 model trucks released in '98 and has gone through several attempts at a fix. One customer I had drilled a hole in the side of the outer shell, installed a grease fitting and hit it a shot or two every time he changed his oil. I'm not recommending that officially since it is modifying a safety item, but it made him happy.

The new ones have been much better so far. I know of a few 20K plus ones that were still quiet.

The same year range mid/full size cars do it too BTW. GM really screwed the pooch on that one.
