I bought a 2010 Taupe Metallic Grey, Crew Cab, Chevy Silverado Z71 last month and I have a question about the rear locking differential.

 

I've never had a vehicle with a locking differential so excuse my ignorance but I am very curious to learn as much about my truck as possible. I want to know what it can and cannot be expected to do.

 

Will the auto locking differential in the 2010's engage when the truck is in 2 wheel drive or will it only work if I am running in 4x4?

 

Any other useful info you think would be helpful would be appreciated. This is my first new truck and the technology in my 2010 compared to my '97 and old '84 is just ridiculous. I am really enjoying my new truck and knowing more about some of its features would give me a lot more confidence in its (and my) abilities.

 

Thanks!!

Does not matter, once 1 wheel spins 100 rpm faster than the other, it will lock and drive with both wheels. It does not work over 20 mph because its not needed if you are going that fast.

 

 

What this

Thanks guys I have been checking the vids out. Nice info. that of course leads to other pieces of info that I've found to be useful and also entertaining.

 

So will my locker work the same way in 4x4 as it does in 2wd? I've always been disgusted with "four wheel drive" vehicles that really aren't 4x4. In my mind if you have 4x4 then all four wheels should be driving at the same time.

 

How exactly does the 4x4 work in the 2010 and also, does the locker work the same way as in 2?

 

Sorry for the basic questions. I can drive 'em......I just can't tell you how they work in too much detail.

It works the same in 2 WD or 4 wd. It doesn't care if you're in 2 wd or 4 wd

The animated vid on the G80 really explains very well how the locker works. I have a MUCH better understanding of the function now. Some of those vids are really interesting on how the tests came out. I try to watch ones that are objective and not done by the brand loyal guys just to show their brand of truck is supposedly better. I've had Fords and Chevys and I like the Chevys better.

 

The G80 comparison vids to the limited slip systems show a huge difference and something I've been craving in my four wheel drive vehicles for years. Are the vids really a good estimation of what the 2010 Silverado is capable of?

 

I actually had my truck in some fairly rugged terrain today to do a little scouting in preparation for this year's hunting season. I played around with the terrain in 2wd and 4high just to see how the truck would respond. I didn't take it into 4low at all. I handled the terrain without a problem and I purposely stayed in 2wd most of the time just to see what it would do. Some of the ruts were easily pushing two feet deep and they were pretty muddy. I tried to stay out of the mud just because I didn't want my truck to get too sloppy but in doing so I had to deal with other terrain issues like good sized rocks, steep slopes, etc. The truck handled them without any problems at all.

 

Maybe after the newness wears off a little and I'm not so protective of it, I will go back into that area and be a little more aggressive. I also had my son who is only 6 with me today. When he is with me I never take any stupid risks in case something did happen and I had to worry about being back in the sticks with his well being to worry about. Next trip it'll be me in my truck and a friend in his Jeep. Then I'll feel more comfortable in trying a few more challenges.

 

I have some funny stories from when I was a kid and my Dad and I would go on our outdoor adventures. He loved Fords and I remember when he got a brand new F-150 in the 70's.....his famous last words were "Fords climb trees!" (said as a joke of course) And when we broke our front axle and got stuck 30 miles back in the woods on a remote power line, and when we were on the beach and sank into a soft part of the sand just before high tide and the truck was eventually covered in ocean up to the Ford emblem on the grille b/c we sank so deep not even tow trucks with winches could pull us out.......well that "Fords climb trees!" slogan came back to haunt him and his friends recalled it for him many, many times in friendly banter.

 

For me......I went with Chevys and I always hear my Dad's voice when I am thinking about doing something stupid with my truck. :jester:

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Getting greedy...   The AC pump has been replaced at least once per service records, and it's been recharged twice since 2018 or so, in approximately 2 year intervals between those charges.   It was done at the same shop...clearly they were enjoying the revenue of recharging the system periodically versus actually tracking down and fixing the leak. I learned that the owner was 88 years old when she passed in 2023, so maybe they assumed only a temporary fix was needed anyway.   The system is basically empty now, the compressor spins freely, so I'm guessing it "just needs a recharge".   I vacuumed it down, and it has basically held overnight. Doesn't appear to leak under vacuum, check! So it must leak under pressure. I don't have a way to pressurize the system and pressurizing it with shop air wouldn't be great for the air dryer (which is probably toast anyway?)   The dryer (accumulator? I'm not an AC expert) has a Schrader valve, but the high side has an old ball-type valve, which are notorious for leaking. It's clearly had schmutz blown out of it at one point because the line/area next to the valve is coated old black crud, which I assume is AC refrigerant residue/oil, or maybe even dirty dye. I think I'll roll the dice and replace the valves. I have a black light around here somewhere so I'll find it and shine it around the engine bay in the dark to see if there's any dye.   I can't think of another way to track down the leak other than injecting some dye (if it doesn't have any) and having it charged up. We can't buy R134a off the shelf here anymore, so I'll run it up to Jiffy Lube and have them do it. I think I have a coupon. At the very least, the charge should last long enough for a year or two, according to history. I think this truck will be long gone by then. But cold AC is a selling point.

      6.2L L87 Powertrain Engine Noise (Lifter Failure) Question

      By clowe1243 · Posted

      Got the truck back today.  Called them yesterday to get an update, and miraculously my truck is finished?!?! The $13k out the door was complete bullshit!  Ended up being over $14k.  They added some bullshit service bulletin that I cant even find, where they replaced my radiator without telling me or asking me, and charging me for it.  Need to do more research into it, cause they leaked the first delivered radiator was ran over by FedEX.  Sounds like bullshit to me. 2.5 Months for an engine swap, which ended up being remanufactured, not new; ****ing ridiculous.  Brakes are squishy as hell, not sure if its from sitting.  Will give a couple days to see it that figures it self out.  GAVE IT BACK TO ME WITH 1 GALLON OF GAS!  Just filled the tank the day before drop off, more bullshit.  My dash cam SD card was formatted, not really much I can do about that. 3 year, 100k GM warranty at least.  Time to sell it and say **** off to GM.  Bad experience.  Cant wait for the survey email to come through.  Overpriced Raptor R, here I come!

      Radio Update

      By haoleboyZ71 · Posted

      If I forget the phone in the truck, and forget the truck in the phone, and reconnect.  It works great for the day.  Truck sits overnight, and the next day is a no go.  It will connect Android Auto via usb cable, but not bluetooth.   Ive tried Everything in this thread so far, and nothing works for more than a day.   I think I might have to go to the dealer and have them flash the pcm.   thanks for all the suggestions guys. 👍

      primary drive belt tensioner

      By Bill Lemmond · Posted

      2022 2500HD Crew Z71 Duramax single alternator.  Recently had the primary (water pump / fan) belt tensioner pulley bearing to fail while hundreds of miles from home of course the plastic pulley melted and belt shredded which took out some wiring. Found a replacement tensioner assembly and belt to continue now would like to find a replacement for just the pulley and bearing to have a spare assembly in case of a repeat, the rest of the tensioner is fine. Has anybody here found a correct replacement part for just the pulley and bearing? Any help is appreciated.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Atlas · Posted

      +1 for the 3.0   Perfect for 1500 pickup towing duties.   Perfect engine for a 1500 pickup period. Huge torque at stunningly low RPM makes it feel a lot lighter than it is. The fuel mileage is insane for a tall and heavy 1500... 30+ on the highway. Mid 20's around town.   It's probably not perfect if you bought a 6.2 for the braaaaaaapppppp V8 noises and wrapping it out to 6k. The LZ0 acts and sounds like a small turbo diesel and there's nothing you can do to make a small turbo diesel sound like a big one, and you can't make an inline diesel sound like a V8 diesel/big Duramax. It's a different driving experience altogether.   Drive one, I think you'll like it, though...
