Probably alignment issue. See attached TSB - removes 2017 from the bulletin. PIT5501F.pdf

Potential update to all issues regarding steering and Chevy's new recommendation. Seems as though they are abandoning the PIT5501 thread and replacing with this: see attached. 4502540.pdf

Which TSB? I saw reference to a few different ones on here. Where can I get a copy? I have the same issue even after having my entire steering box replaced and the factory idler and pitman arms. Thanks

I have the same problem and truck was manufactured in Flint. I initially had 7" or more play in the steering, especially at higher speeds. As for the steering box replacement fixing the issue - Nope, it doesn't. I had mine replaced with only 1815 miles on it and still had the problem. To potentially help others here, this what my tech wrote: "Steering gearbox has excessive movement in input shaft before output shaft begins to move. Gear damage within gearbox. Replaced hydraulic recirculating ball steering gear replacement 7421780." Tech said my gears were "trashed" but they never looked up or referenced any TSB (this must be a common problem so why didn't he know about the TSB?). Truck was warrantied and cost me nothing - BUT, it wasn't fixed. The truck was stock with no modifications. At 3650 miles I took it back in and was convinced by the tech that since I had lifted it that I damaged both the idler and pitman arms and that they needed to be replaced - this is AFTER he test drove it and reported back (on the service order) that he didn't find the looseness that I described, and, that I wanted the two arms replaced. Replaced both on my nickel b/c of the "now not in warranty" issue and $1000 later it still has the same issue. I had the guys that lifted my truck mark the idler and pitman before I removed them to make sure that they were from my truck (I asked for them to be returned so I could have them inspected). Although the tech told me that this was the "reason" I felt the steering was loose, there was absolutely nothing wrong with them other than a little rust. I need to add that the tech told me that "some looseness" was common for a 2500HD. I've been driving it, but only around town, since and now have 9000 on it but will be taking it in this weekend to have them find the problem and fix it - even if I have to pay out of pocket. I'm making a list of all the suggested reasons from this board and will give them to the service manager to have them explore each issue. Does anyone know if digital assist can be disabled, or has anyone tried that?
