This truck is my first 4WD/4x4.  So a few weeks ago, I put my truck in 4HI, to drive in the snow, no issues.  Put it back into 2WD, when I got home, and haven't needed it since, until this afternoon.  When I put it in 4HI, it was grind/vibration central, but when I put it back in 4AUTO or 2WD, there is no issues.

I would cycle through all modes, including 4LO, and each time drive forward for a short distance, then in reverse, then forward again, then disengage each setting working back to 2WD.

I'll try that tomorrow.  Transfer Case has a separate servicing, right?

Yes, transfer case, transmission, and rear end.

 

All 3 listed in your owners manual service section.

 

Opinions on the site will vary on mileage and what type of fluids to use on each.

Took it into town this morning, ran it through 2WD, AUTO, & 4HI, didn't touch 4LO since I was pressed for time.  Driving straight ahead, no issues.  Was going to run them through in reverse, when I got home, but I shifted into 4HI as I was coming up my street, turned to line up on my driveway, GRIND and seemed to "lockup" as I continued turning the wheels, so I stepped it back into 2WD, and finished backing into my driveway.  As stated before, I had no issues a few weeks ago in 4HI, not even when I made any turns.

Dry pavement today?

 

Not good for the 4WD drive system, since the front wheels are locked and trying to turn at the exact same speed while you are turning. 

 

Need to have a little speed built up, makes it a lot easier for the system to turn freely, slow turns, and it likes to bind up.

Ok, explains why I didn't notice it in the snow a couple weeks ago, but I was on dirt when I experienced it Saturday.

You probably had enough grip in the dirt, especially if you were turning slow.

 

Not an expert, but when I use mine at our beach house, I always start out in 2WD, get rolling and then shift into 4HI at speed (slow, am on a long inclined dirt driveway) with the wheels straight before I make any turns.

      2017 Chevy Silverado 1500 4X4 Goes into gear but won't drive
      By ChevyGirl777
      Hello, I have a 2017 Chevy Silverado 1500 4X4, 110,000 miles, was driving down the road and suddenly stopped moving, truck still on but won't move. Goes into drive and reverse but wont move. No check engine light, transmission fluid full, and clean, no crazy noises. Any clue what it could be? I have been told the linkage, or the transmission pump... Any advice is appreciated.

      TSP stage 3 cam questions
      By NicNakPatiWak
      Hey Everybody. I’m about to have my 2014 Silverado AFM deleted with stage 3 cam upgrade, longtube headers, l86 intake, l86 TB, 3200 stall, custom tune. My question- is their other things I must do to go with these upgrades? Truck is 4x4 but will soon be lowered. Driveshaft? New Trans cooler? Bigger oil pump? Any help would be appreciated. Thanks in advance

      Lowerdz Static Slam Daily
      By Lowerdz964
      So after some digging I found the build thread section. 
       
      What we have here is my 2014 Crew Cab Z71 4WD short bed queen. Bought a few years back as my daily work truck to put my weekend warrior back in the garage. When I first snagged her she was lifted on 34s and by the first drive home I knew the tranny was blown. Worked out a deal with the dealer I bought it from and had a 100k warranty remain installed where they paid for half of T&M. Factory crap struts with spacers front to rear came on her for a "lift". Within a few months I installed ICON Stage 1 kit to give her that quality ride effect. Love me some ICON, ride was supple on and off the road with this kit. When I decided to let go of the weekend warrior to fund the wife's new ride and changed industry's I got the itch to go back to my roots and slam her. I know I wanted to follow the same concept I did with my last mini must haves.
       
      Suspension must haves:
      Adjustable Coil Overs up front Adjustable emulsions in the rear (I went back and forth for months if this was needed on a full-size before realizing it was a MUST HAVE) Control arms up front due to 4wd and limited spindle offerings  Flip in the rear 22x10 that sat flush if not almost flush and this go around the wheel set had to be SQUARE  
      After quite a bit of research I came up with the following mods, mind you not all at once
       
      Mod weekend 1:
      IHC 4/6 drop kit Front and Rear, dialed (according to my comparison from ground-to-fender measure on a 19' Z71) she sits right at 4/6 and within spec on alignment.
      IHC 4" drop arms (Front) Belltech 2-Way Adjustable Coilovers (Front) IHC Axle Flip kit (Rear) IHC 1" lowering shackle (Rear) IHC drop shocks (Rear) Wheels and Tires 22x10 square ET +0
      Cosmis racing XT-206R (finish chips easily but they also clean up easily) Lionhart 285/40/22 (Surprisingly nice ply and quieter than anticipated)  
      After the initial mod weekend truck sat with a Carolina Squat 🤮, the rear shocks had no ass in them and my measured adjustment on the coil overs were perfect however I did install per IHC instructions with the 1/2" spacers raising the front 1". Trucks rear was as soft as a yellow belly teenager, I would bottom out axle to frame and pumpkin to bed every where I went. This was not my experience on my first go around on a full-size (96' extended cab bow-tie w/ 2/4). I was able to load that rear end up with dirt bikes and motors all day long without issue, guess there was a leaf design change over a span of 18 years 🤣. After a week of banging down the freeway I pulled the trigger on IHC helper bag kit and QA-1 shocks within spec of the drop shocks from IHC (eye-to-eye extended and fully compressed). I made the mistake of purchasing Belltech adjustable drop shocks, these only work for 4" rear drops to my dismay 😔. I also noticed that the drop shackle in the OEM hanger configuration was rubbing at ride height, so purchased the shackle flip kit from IHC as well.
       
      Mod weekend 2:
      IHC Shackle Flip Kit (allows for cleaner travel of suspension, simply shoving lowering shackle onto system was rubbing frame) IHC 1" drop shackles IHC Firestone helper bag kit (Rear) QA1 2-way adjustable emulsion shocks (Rear) Designed and Machined custom bushings to accept the OEM bolts (Inventor and Xometry FTW)  
      Once I installed QA1's, shackle flip, helper bags, and removed and readjusted coil overs I got her squatted on all 4 corners EQUALLY. I rub in front occasionally on full lock to drivers only and over excessive dips in road mostly in front. I have bumped coil over adjustment up 2 clicks from factory on drivers and 1 on passenger. I have compression up 2 clicks from middle and run helper bags with 8-10lbs in them when bed is not loaded up. Rarely do I ever bottom out these days, usually if I have the truck loaded up with people to hit work lunch.
       
      Sound System:
      I upgraded the sound system at some point in time between ICON's and slamming. This has been an ongoing mod debacle on my end. Started by building a steel rack behind passenger seat to mount three Memphis amps. I was using 3 Memphis amps I had from my old truck build, however the front amp decided to start sending unwarranted signals to the speakers and the rear amp after about 3 years of sitting and 6 months of using decided to finally die after an overall 10 year party in 3 different rides😒. None the less the two AB amps were replaced with new Memphis hardware while the class D (knock on wood) keeps trucking along. Doors received focal 3-Ways up front and 2-ways in the rear. Class D memphis runs a sundown 10 under the passenger ina  semi-custom box, added some height to the magnet area to accept the depth of the sundown 10 that runs on 1ohm. Memphis feeds it something like 800 watts rms @ 1ohm. Oldy but faithful Pioneer double din is running the show after trying 2 other setups to use the stock head unit. I initially tried pioneers CAN module but making fine tune adjustments or simply turning off the sub for when the kiddo is in the truck was a painful operation. Switched to an AXXES CAN setup, access to this was great, all the adjustments were perfectly accessible, however my trucks CAN did not like this system, I was getting all sorts of weird can signals and issues throughout the truck that I finally ripped that out and sent it back after trying two different AXXES units.
       
      Exterior:
      2nd year into ownership finally replaced the factory grill with the OEM paint matched honeycomb and updated the fogs and headlights with RIGIDs and paint matched 14-15 style headlights. Also threw in TRLS HID bulbs while I was at it and TRLS rear assembly's as well. I am an avid mountain biker so finding an easier way to load up the bikes was a must, when the pand hit I pulled the trigger on the RIDE88 truck bed system as they were doing a 25% off on preorders. Best investment for a biker ever, so easy to load and lock the bikes up, only painful when I have to fully utilize the bed.
       
      Performance:
      Stock 5.3, that is mostly clapped out, so I have not gone ham under the hood. Initial purchase was an air raid intake using the stock box as most factory units pull outside air vs "cold air" tech. So installed the AirRaid intake tube that ditches the sound deadening box and did a drop in oil filter. After much debate, about a years worth, I pulled the trigger on the MBRP side exit exhaust. I knew from the day I started the truck with it on that I absolutely HATED it but for some silly reason I left it on. Now I am in search of an OEM exhaust so I can throw this junk away and do an electric dump out later on down the road.  Eventually I will be swapping the 5.3 out for a LS1 or LS3 depending on what comes available next fall (waiting for prices to drop) and I will replace or rebuild the trans and will 100% replace the transfercase (culprit to my Chevy shakes when auto mode engaged) but first I need to finish my latest weekend warrior so I have a new daily while this ol'gurl is down.
       
      More to come

      frame swap options
      By stevenv76
      I have a 2007 1500 crew cab classic that I've done more restoration and customization to than I really would like to admit especially with guys that truely understand these trucks.  I went way to far because I needed a truck to haul more than mine should have done and refused to get rid of it.
        All that being said, my frame is rusted to the point that repairs are no longer going to cut it.  I've replaced 1 cross member, boxed in the back half with 10 gauge steel, added braces but now the cross member above back tank strap is rusted off drivers side as well as the large one under rear of the cab and it's trying to fold on me.  I've replaced all bushings on control arms, tierod holes modified to accept hd tierods, new CV axles, front diff gas new outter bearings and seals, new ujoints in front and rear shafts with the rear being a steel shaft that is rebalanced.  freshly build transfer case with pump guard, transmission has an upgraded trailblazer 2400 Stall converter so about 2700 in the heavier truck, input shaft for a 4l65e, redline wide bands, Corvette servo, 9 plate clutches and hd bearings.  the rear diff is a Yukon duragrip, swapped from 3.42 to 3.73, 4 wheel disk with drilled and slotted, gutted the cats with a 3" stainless mbrp  installers choice cat back single exhaust, ho premium tune. I also installed a 5000lb load/lift airbag system with pump and tank behind the rear seat and guage/controller in the dash.  body is completely redone after being tore down to the driveline and cab bring only thing left on the frame so I was already half way there 3 years ago. 
        The big question is what year frames can I use frame wise.  what will be the cheapest option in everyone's opinion?  living in northern Michigan, finding a used one local is kinda dumb in my opinion because you're going to be blasting a ton of rust off at 5he least so why go through the work of swapping with another. one that is already half way gone.  will either be driving to get one or having shipped.  somewhere between me and Arkansas would be best as I have a friend that makes that trip several times a year.  of course money is tight especially with this hog costing me 51¢ a mile in just fuel the last couple weeks.  I'm seriously leaning towards wanting to do a swap with a frame that has the harness attached still.  I'm having electrical issues from hell to boot.  gas gauge hasn't worked since 2018 when I got it and I've tried everything shy of ecm(I did try bcm and tcm), I've got a bad wire somewhere in harness for bank one and also to the tps.  I play with those. wiring harnesses if it starts to run bad and it smooths right out but have no clue which wire is to be the culprit and pinpoint the break inside the sheathing.  the biggest ****** there is 07 classic is a complete Frankenstein from the factory.  the engine is flex fuel capable but no active fuel management which all the fuel components are the same as 08.  the oil filter is ordered by 08 to make sure I get the right one.  suspension parts I just say 06 on.  half the all cab wiring is ob's so I don't know how this all plays out harness wise.
        I parked it under a big tree Thursday that had a ton of very large dead libs during a severe windstorm and nothing but a nice live tree did fall right where I had it parked prior and no I can't make this ****** up.  I'm over insured and was hoping for a little help with my decision on this thing.  
        sorry for the rambling guys, just wanted all factors to be known when advise given

      Issue with 4x4
      By Jomar
      My Silverado is having issues with the 4x4. It does Engage but it struggles. When I set the 4h it kinds of drags like something is holding it back and it makes a weird sound coming from the front end. If I set it to 4l it really doesn’t want to move. I have to give it a nice amount of gas for it to go but is feels like something is holding the truck from moving. I’m looking for ideas to pin point the issue. Thank you
