intermediate steering shaft on 2006 Chevrolet Silverado 2500 HD

I would like to replace my intermediate steeing shaft. I have read that I would have to used a j42640 steering column ati-rotaion pin. What is that and how hard is it to replace this my self?

The steering column anti-rotation pin is just that, it's a pin you insert into the base of the steering column to keep the steering wheel from turning while you have the intermediate shaft disconnected. If you do not use the pin the steering wheel can become off center in relation to the steering column Air Bag clock spring (the clock spring is the electrical connection which allows the circuits in the steering wheel to remain connected while the steering wheel turns). An off center clock spring can be damaged when turning the steering wheel after reconnecting the intermediate shaft. The intermediate shaft on your 2006 Chevrolet Silverado is not very difficult to replace and it can be done with out the anti-rotation pin if you are VERY CAREFUL. I have used a couple of strips of masking tape from the top of the steering wheel to the dash board to hold the steering wheel in place.
Thank you very much,
