I used the same valve that Gm but All I did was move it up above the frame. Also, GM communications is a terrible source.

    Always Different has a point on that one. And if it was an issue, do you think GM would message you and say "oh ya we didn't think this one through, its going to break". No, absolutely not. Its definitely a cost avoidance measure on their part. It will fail 100% over time but you'll only hear of it happening to a couple of them. Why? Because lets be real, only a minority of these truck owners are going to be using their truck for offroad purposes, and I'm sure that's what GM is betting on. Why spend the extra $100k in tubing over the span of these trucks being manufactured when the average customer isn't going to submerge their truck past the tread. It costs $5 and 30 minutes of your time, for this mod, to rest assured you're not gonna have to deal with the warranty procedure later on in the trucks life. Why not do it? Gotta say, love the channel, but this really sounds like a shill take on it "GM said its fine, so its fine". Give me a break.

    Tim - the '17-'19 ZR2s had this vent line extend up to the gas tank filler area. This looks like a cost reduction by the bean counters to me. Therefore extending the line would be a lame attempt to decline warranty. Same functionality and the dealer should have to prove functional deficiency of the mod to decline warranty imo. Regardless I am 'risking' the mod for my Bison to keep the vent out of the mud.

    Better safe than sorry imo, if planning to ford water & mud & have a 2locker gm twin, get some hose & a couple hose clamps & sure, prob even a few zip ties. If you're really a car guy chances are you have this stuff just sitting around already, I do. GM's system is the cap, not the hose, no doubt about this one. Up much higher the cap will clog much slower, can't avoid it. Count on mfgr warranty's being honored & dealers applying fixes reliably(?), prob not. Imo Always Different is absolutely right in this one, nobrainer. Make sure your hose length accounts for full susp travel, good clamps well tightened, diy, the fix yourself, go wheelin. Avoid repairs, Nobrainer. This bud's for you.

    @DrewJHarrison 8 місяців тому +4

    I have spent over 20 years in the vehicle development and production industry and can guarantee that the shortened tube is likely a cost reduction effort and for ease of vehicle assembly. Yes the "Gore Tex" type valve may be adequate to prevent water ingress and pass GMs validation requirements which have been developed over decades to reproduce every possible use case of a vehicle, so the likelihood of a failure of the system is improbable but not impossible. However I will say from direct experience with similar vents they are susceptible to getting clogged over time given extended exposure to salt and dirt. So it may be unlikely to get ingress but there is still a risk over the long term that you lose adequate ventilation which could result in premature failure of seals due to pressure differentials built up in the housing. I see no harm in this particular case in relocating the vent to reduce the likelihood of blockage, I would just be careful of the routing to ensure it doesn't get pinched or snagged.

    We will know if GM engineers were right or wrong few years after the warranty expires and everybody cries out when replacing these diffs. So, let me just repeat what I think those engineers are telling us: This breathable tech marvel is BETTER, it esthetically makes the underneath of the truck more fashionable, so it compensates the hanging shocks. I buy all of that, but is it cheaper than a longer rubber hose? (This is the part I do not understand).
    Seriously, it just does not make sense to me. Why are they recreating the wheel when they can just put a longer rubber breather for the fraction of the cost of this thing?
    Also, I live in WA state and I have had at least five GORETEX jackets, if not more, and those jackets work for a short time and after that I have to buy special detergents, go through b*****t process to rejuvenate the stupid GORETEX, and it still does not work. I understand that breather thing is not exactly the GORETEX technology they use (maybe it is). I am just saying - customers are not stupid GM. Just because we buy your products, it does not mean we are stupid (or maybe it means exactly that). And if that is the case, I will go and have a beer, which will help me get over this nonsense.

    • @BowTied69
      @BowTied69 8 місяців тому +1

      It's cheaper not only for the length of tubing, but easier to install. The early 'rado ZR2s had a breather tube that went up by the gas filler neck. This was a cost reduction that I would blame on the bean counters, not the engineers. This change works for 90%+ of customers that don't do real off-roading so it makes economic sense. That's my take on it.

But, Chrysler products, well they have different issues, every damn year." Toyota is still among the best, but even it has had a lot of challenges in recent years as it met the production volumes of the market leaders. Meaning they all have issues now. I think the big problem is the bean counters look at the average time the first owner owns a vehicle and they design it to last just a bit longer. They care nothing about the 2nd and subsequent owners, only the customers who buy new. Then cost reduce - save 25cents on a part is a lot of money on 10 million vehicles; cut it to the bone.

      @@BowTied69 VW in Europe did that. Their cars are relatively reliable within the the warranty period and as soon as the warranty expires, the pain for the car owners start. It is basically the crappiest car company in the world right now (I am exaggerating here - of course there are worst car makers than VW, but VW is pretty much on the bottom of my list).
      However, Japanese car makers design their cars in a way that the most parts last the life of the vehicle, and with Toyota it is a bit or much more (sometimes a life of the vehicle times 1.5 or 2x+).
      If you have noted, although anecdotally in my case because of my small sample size, people generally change a part or two of their American made cars (from the Big 3), so the car can last a really long time but the owners do refresh (change) many parts quite often compared to their Japanese counterparts.
      On the other hand, If you own a high mileage Japanese car, you start changing parts at the end of that car's life duty cycle, and it seems that you fix one problem and the next one comes up, and in a matter of a short time frame it feels like all of the car breaks down at once.
      Toyota lately has their own issues mainly because they have changed models entirely. In their current offerings, if I am not wrong, only the 4Runner is quite old, maybe the Lexus IS and GS too, but I am not following Lexus so I could be wrong.
      Toyota cars have issues because they implement new tech and have to catch up with the others. People like new technology and I participate in these owners survey a lot, so even more tech is coming.
      I do not like new tech. I am old and that is why I have a 2021 Toyota Tundra - an old truck with an old soul, but new blood.

I have seen previous vent designs not survive long term with mud/rust - relocating the breather is such an easy mod, it makes sense to me.

      ZR2 - Up to 71 cm (28 in)

      I'd imagine the bison to be maybe 1.5 in higher then the base ZR2 so (29.5 in). Personally I'd be more concerned about washing out the grease in the hub bearings at that point. What I'm trying to say is any fording is gonna reduce the service life of submerged components.

    I wonder what was GM’s reasoning behind getting away from the simple, old style, vent that extended above the frame rail to begin with? Did the R&D $$$ that came up with the stubby membrane hose pay for a few feet of hose they’ve saved? I suppose you could just extend the stubby vent hose above the frame.
    In the end, if the dealer finds water contamination in the rear end, they’re likely blame it on the owner even if you left the OE vent hose in place. Probably call it flood damage or abuse, deny warranty & tell you to claim it on insurance.

      The supplier is likely a 3rd party. GM loves to tell their suppliers, "Sharp your pencils." That means winning bid is the lowest price. Fractions of a penny add up to a lot of dollars when you're supplying a part for 1 vehicle for 12 years and the sales of that vehicle exceed 250,000 per year.
