Always check steering joints before changing the steering box.  Idler arms would fail before a box.  This was my problem.

Any updates to this? I have a 2016 Duramax 4x4 with 40k miles. The last 1000 miles it’s got the death wobble if you hit a small bump around 40mph or so. It tracks completely straight at high speed. It’s had an alignment  and  I checked all the front end parts and everything is tight other that the steering box. The dealer said it’s on me to fix since I’m outside 3/36 I’m pretty irritated that this happened so early. I have a 2.5” rough country and running 33s I’ve had them for 2+ years no issues till now. It also has 2-3” of slop in the steering wheel. Thanks.

I’m having same issues with my 2016 Sierra Denali with duramax. At 7k miles developed lots of slop in the steering wheel, took it back to the dealership and had the problem “solved” under warranty. Since then I have installed a 5” zone lift and 35x12.5 tires with -25 offset. Truck drove great for about 7 months and started to notice the slop back in the steering wheel. Just took it back to the dealer and said I was out of warranty with 21,650mi on it and said that the larger wheels are what did it and will cost me $1800 parts and labor for new steering box and pitman arm. I refuse to believe that a he can’t handle larger tires. And I have zero desire to spend $1800 just to get it back to stock and potentially have this issue again in a few thousand miles. Anyone have a viable upgrade solution to this issue?

The wobble your having is your brake rotors. All makes of heavy duty trucks have the same issue after getting on the brakes hard for an animal crossing the road or holding the brakes to long with a load on, basically overheating. I put a set of slotted and drilled rotors and matching brakes in the front and it all went away and never came back. Some people do all 4 but I’ve had two trucks that I only did the front and they’ve been fine. When it comes to the steering being stiff, I’ve had it on both trucks. Boys at the shop looked at it and said everything is more than tight, but the lube shop missed a couple grease nipples and that helped a lot for about 15k. If I wash the whole underside of the front steering components and brakes, it also goes away for awhile. Can’t pin point that issue just yet

So as the very first post asked repeatedly;has anyone found the actual solution (or the cause at least)?NV8 RPO appears to be problematic box code(whatever vehicle/colour/trim)TSBs issued and fix appears to band aid a problem.Where did the “play” come from other than wear.Adjust out the slack does not account for the new “space/play” that was created over time.(I assume metal filings in pump/hydro boost system after endplay adjustment made.Partial flush from box removal/replacement.Suspect the GM replacement boxes also have the same basic issues.NOBODY seems to actually know root cause(ie:gear hardness/metal deficiency/fluid inadequacies/pressure or flow problem/contamination from manufacturing processes.Endless forum guesses but zero facts or fixes and alternatives put forward.

    • Two interesting tidbits of information which are NOT related were just released.   One, regarding the possible thrust bearing issues / engine failures with the 3.0. Demonworks just did a segment in which they believe they may have found "a" or "the" cause of thrust bearing failures: A missing thrust bearing. If the engine doesn't have all its thrust bearings from the factory, the missing bearing can cause extra play which ends up destroying a nearby thrust bearing which then sends metal through the engine.       Of other importance, Lake Speed Jr released some interest information regarding oil weight selection for the 3.0. Comparisons of:   AcDelco 0w20 Dexos D Mobil 1 ESP x2 0w20 Dexos D Mobil 1 ESP x2 0w30 Mobil 1 ESP x4 0w40. Mobil Delvac 5w40   Spoiler alert: The Mobils are PAO Ester -base and the ACDelco is a Group III base. Mobil shows lower wear in their tests for similar weights. Additive packages between 20-30-40 weight ESP's appear to be the same, but only 0w20 is Dexos D licensed. Wear is even more reduced with 30 and 40 weight ESP although all perform very well and resist shear and provide very similar viscosities within temperature operating ranges in the 3.0.   There are even more surprises, so just go watch it.    
    • Hello Guys I'm new to the form,         I just put a 7-inch Rough Country lift on my 2016 GMC Sierra 1500 with the 5.3 and I also put a Borla exhaust on it. But I noticed when I'm in park or in neutral and then I rev my truck up really quick there is a bad click noise and I think it's coming from the motor somewhere. Anyways I got a video of it I will attach below I was just wondering if you guys think its rod knock or lifter tick or something like that because I know the AFM kind of made the lifters weak on these trucks.       Thanks!!!!!

    • We’ll have to agree to disagree. I didn’t experience or know anyone who had a decent car after 100K miles in the 60s through the 80s that were daily commuter vehicles. Unless they were collector vehicles. Of course things cost more due to inflation. But we also make more money. The biggest money drains these days are things people think they need today versus what we require back in the day. Like cell phones and internet as examples. Another example is where you live. Cost of living varies from state to state. I would need twice the money to live in NJ vs Texas in retirement. The car you recently purchased was less than my first car with inflation at 3000$ in 1973. I didn’t have air, electric windows, cruise etc. Purchasing power is equivalent, you just have to do the research. 
    • Sierra HD Pro:   - If you want a power driver's seat on the Pro, you can't get it.  You have to go to SLE.   - Factory remote start?  Can't get it on any of the Sierra Pro trim (1500 or HD).  You have to go SLE.     - 7 inch radio has limitations for replacement if you wanted to upgrade the screen, etc.    - Steering wheel radio controls?  Nope.  Can you add them?  Yes.  NOT CHEAP.  Requires a new instrument cluster, steering wheel and wiring harness mod kit.     - Fog lights?  Nope.  And no factory path to install them.    Sierra HD SLE:   - IMO, the larger radio screen is a much better interface.   - Fog lights?  You can get them.  Steering wheel controls?  Has them.  Remote start?  Yep.  Power driver seat?  Available.       Silverado WT:   - Same as the Pro above however you CAN get factory remote start installed at the dealer for the WT Chevy.     Silverado Custom:   - Comes with 20" wheels only.  Can you swap later?  Sure.  But.  Truck is calibrated for the stock 20s (34" tire) and no path to properly recalibrate.     - Power seat?  Yes.   - Steering wheel controls?  Same as the Pro above.  No but can be done and not cheap.     Silverado LT:   - Same as the SLE.  You can get or it comes with many features you can't do on the lower trims.       I'd say its all going to come down to what you NEED and what you WANT to have that you'd benefit from.  For me, things like power seat is a must (I hate the WT/Pro seating position), so I'd have to go Custom, LT or SLE right out of the gate.  Steering wheel controls?  Should be standard in 2026 across the board IMO, so again, puts me to LT or SLE.  
    • I have a 1500 but the Custom trim. I bought it solely for the simplicity meaning less electronics. I also love the old school gauges. The only thing that I like about the LT better than my Custom is the front grill. Otherwise, absolutely no regrets choosing this trim.
