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.
Hey everyone, got a question someone might be able to answer. I've got a '14 Silverado 1500 WT. At the back under the bed on the driver side near the spare tire is a wire hanging down with no end. Originally thought it was a frame ground because the outer casing is black but today I took a pair of wire stripers and found that there are 3 thin wires inside of the black sheathing. They are Solid Red, Solid Yellow, and Solid Black. All lights on the truck work, the trailer lights all work when plugged in too. Anyone have any idea what this could go to? I currently have it rolled up and ziptied to the frame. Thanks for any help.
I am wondering if anyone can take a look at their 2014-15 headlight assembly and let me know if their headlight assembly moves. The assembly that the light bulb turns into moves in/out slightly. Not sure if this is normal or if something is loose/broken. Thanks in advance!
Hi everyone im new here and need some help. I have a 1990 gmc sierra 3500 4x4 and yesterday i was flexing while 4 wheeling and noticed my front right leaking gear oil. I looked closer and noticed my right side inner axle popped out and wouldn't pop back in. So now it is loose inside and leaked all the gear oil out. Im thinking it could be a c-clip broke? But i was told my truck doesnt have those.. any help would be much appreciated thank you..
