10"

So i got my truck back and it seems great thankfully ! They had it 5days. Its hard to read the work receipt but they did bulletin D which may or may not include these parts also listed on the sheet , Pitman arm, shaft, gear , front end alignment. There was no charge. I had no steering from 11-1 on wheel. I have 100 miles since pick up and all seems fine. I am going to check my power steering fluid for metal.

I believe first time i notice freeplay in steering ,plow was up. I turned keys up one turn right when i got truck (March 2016 thinking i was putting plow on). Didnt end up putting plow on then so drove 15k miles pulling and hauling heavy loads with no problem. So I had plow put on November 2016 with 15k on truck. I was driving home with plow on and steering went to hell. Thought it was wind blowing on big plow . Then thought plow assy place might have tapped into wrong wires making stabilitrak light go on. Then when i took plow off and drove down road i notice wow truck still has no steering from 11 to 1 and maybe more 10-2. I own a big truck garage so we looked front end all over no loose pitman arm or any other parts that we noticed. Im not saying we couldnt have missed something, but we didnt see anything. I did have the loud clunking noise that a man has in a video earlier in this thread. SO I feel its not parts related on mine i feel is electrical. BECAUSE I can hold traction control button down to delete stabilitrak and it seems to steer fine at any speed. So if i had worn out parts i think it would affect me at all speeds. Anyways hope chevy garage fixes it or ill trade for another one. I am a die hard chevy owner and have worked the snot out of chevys and had great luck so I wont let one GM problem scare me yet. haha

My eleventh digit is Z so mine was built in Fort Wayne. Looks like the first one i have seen in this thread? I remember most were Flint.

Without me reading back through 19 pages can someone tell me the vin info I need to see where my truck was built.

Yes I did only notice my steering went to heck after the plow had been installed. Im looking now to see what vin is to where it was made. No i have no lift ,truck is stock but does get worked. I did turn the bolts that push the keys up 1 full turn before having plow mounted.

So here I am in the same boat with all you guys. My truck is in shop as we speak. 2016 2500HD extended cab, Duramax . So my truck went for approximately 15k miles and 9 months old before I got the loose wheel feeling. When it started I had just put plow on and the "Stabilitrak" light is lit on dash. I have been researching stabilitrak but nothing about steering. I own a garage and we looked front end over very close as I thought it was falling apart. Basically my pitman arm and everything we could see is tight. But i do have the clunking noise like the video earlier. I have never taken a new vehicle back to the dealer we always service our own vehicles. I decided to make appointment at dealer. Dropped off today and explained problem. The called back few hours later and said they found bulletin ( i hope D). Said they ordered parts and i believe he said pitman arm, gear , etc.? The parts are coming to them tomorrow he said even though its Sunday. Said they will have it done Monday. I hope so and i pray its right. I am leaving for Florida hauling a load in 3 weeks. The chevy dealer is a actual commercial truck center for chevy so i have some confidence they know whats happening. I dont know if I will ever have faith in the fix??? Thanks for all the info on this site.
