I know there are a few different forums on this topic, but they seem to have gone dead. The steering in my truck clicks and clunks especially at low speeds, and the truck wanders on the highway. I am constantly holding the wheel to the left or right to go straight. I have had the intermediate shaft replaced per the service bulletin. After it was replaced some of the noises were reduced, but not eliminated and the truck will still not track straight especially at highway speeds. It almost feels like a bad tie rod end or ball joint, but the dealership said everything is nice and tight, and I checked just for my sanity. I also added a steering stabilizer in hopes this would help. Is anyone else having these issues, and have you been able to get them fixed? 2020 Silverado LTZ with 6.6 DuPIT5809.pdframax

I posted this in the 40 page thread but wanted to get a new look so I copied it here. I have a 2017 Denali 3500HD with "loose" steering. I don't usually give my resume' but I think it is relative to this subject. For 12 years I was a professional test driver at a major competitor to GM. I worked in the suspension development group at a proving ground testing and tuning shocks, spring rates, stabilizer bars, tires, etc. My job was to dial in just the right amount of comfort vs handling vs steering response and feel. Why is this important? Because I am 100% confident I know what is causing my "loose" steering. The problem is the digital steering assist tuning. Although there is a documented issue with some steering gear boxes, the "loose" steering in my vehicle is not from any mechanical problems with the gear box. Please understand that I did not say no one has a gear box problem. I am simple saying that GM has more than 1 issue due to poor steering feel. The problem with my truck has nothing to do with anything being "loose". Here is the proof. At all speeds below 45 mph the steering feels fine. At speeds above 75 mph the steering feels fine. If something was loose or wrong with my gear box or other mechanical steering component the problem would not magically go away below 45 mph and above 75mph. In fact, with almost any kind on mechanical "loose" steering component the problem would be perceived as worse with most increases in speed. For folks with "loose" steering try this. Pick a long straight level road. Drive straight at 40 mph with the steering wheel straight. Concentrate on the amount of effort (torque) it takes to turn the wheel 1 degree, 2 degrees, 3 degrees etc up to 10 degrees. These are small movements of the wheel but you feel immediate effort required to turn the wheel these small amounts at speeds below 45 mph. At 1 and 2 degrees of steering wheel movement there is effort but little to no vehicle response or yaw. This effort is a "feedback" (although artificial and in the suspension tuning world effort is not necessarily feedback but for the sack of keeping it simple let's just go with that) to the driver about what is happening to the steering system and vehicle. Now try this same procedure at 45, 50, 55, 60, 65, 70, 75 mph. Does the effort required to move the steering wheel these small amounts start to increase at 74, 75, 76, 77 mph? If so, you have a poorly tuned digital assist system. In my vehicle the worst speeds are 60-70 mph. At these speed the initial 0-5 degrees of steering wheel movement require almost zero effort. The digital steering is "over boosting" the required assist needed. At speeds above 75 mph, my vehicle "magically" fixes itself and the effort required to move the steering wheel increases dramatically. I have read through all 39 pages of posts. Some folks have described the exact problem I have. "Loose steering" between 45-75mph. Another fact is many have complained that their steering is no better after GM replaced multiple steering components including the gear box. GM needs to assign an engineer to retune the digital assist. I volunteer to help. I just need access to the ability to change the power steering assist levels through the digital steering. So GM if your reading this just look me up and I will help. I hope this helps others to identify their real steering problems. I also hope GM fixes this with a simply retune of the digital assist parameters. Mike P.

Hi there - new guy from Ohio, but not new to GM trucks. I currently have a '95 K2500 6.5TD, '01 Sierra 2500HD 6.0L, '05 Suburban, '05 Tahoe (sacrificial anode). I've had a link to this thread for long while, but haven't joined the forum until today to discuss this. I called our local dealer to get a price on the slip yoke I need for this issue - actually, mine doesn't make a noise, just feels like the drivetrain slumps off every time I go to move from a stop. I greased it years ago when I was replacing the pinion seal and I think it went away, but it wasn't really all that bad, then. Now it's worse and feels awful to drive, so I want to fix. I called the local dealership and after running my VIN, they told me the yoke I needed was 89058878, but it's only $125, my cost. Is there a chance it's not nickel plated? The rest I've seen are approaching the $300 mark for the nickel plated OEM part.
