What year is the truck and have you ever done anything with the ISS?

I would suggest you crawl under the dash and take out the top bolt in the ISS and push it in and out a few times. Then bolt it up and take it for a drive and see if it improves. This was the original fix from GM on my 2004.

I have since replaced the ISS and the bushing in the column and haven't had a problem for quite a while.
