Ok, so looking at the spring part numbers for my truck (2015), it appears that GM has put a new leaf spring (PN# 23287270) under the 2016 1500 Crew Cab. From what I can find, the 2014-2015 1500 series all had the same PN# 23208339. Mine has these as it is a 15 CC 5.3 4WD.

 

Does anyone have any information on the 23287270 spring? If you have a 16, what body configuration does your truck have, leaf spring PN# and does your truck vibrate?

 

I posted a video showing the difference. Sorry about the numbers, I was in a hurry. Told my wife I would run out and get dinner,, ended up a the Chevy dealer...

 

2014-2015 All 1500 series seem to have the 23208339 rear leaf spring set.
2016 1500 series Double Cab has the 23208339 leaf spring set.
2016 1500 series Crew Cab has the 23287270 leaf spring set.

My 2016 crew cab standard bed is - 23287270. Same as above

Do you guys have vibration problems with your truck? Thanks for posting about the double cab 16 with the same PN, I guess it would be good to build a list of all the models the different numbers cover.

I'm driving a 2016 Sierra All Terrain Crew cab. It rides smooth as glass. I'll try to remember to snap a pic of the leafs.

 

My 2014 leafs are noise AF. No vibrations..but noisy. Its at the dealership for a radiator TSB right now, and I'm having them look at the leafs too.

the loaner I am driving is a 2016 Sierra, SLE, crew cab, 4x4, with tow package (has trailer brake contoller), but not MAX tow.

 

The springs have 23287270 printed on them.

Interesting ... my old 2014 leaf springs made noise.. especially when backing up low speed on uneven ground. Anyway... 5 trips to the dealer and they eventually replaced the springs and shocks. The fix latest about a year, when it sounds came back I traded for a new 2016.

 

The new 2016 has been perfect for the first 3,000 miles.. and guess what? Yep, the same sounds from the leaf springs have started ( although not as worse yet) Unbelievable.

 

my 2016 double cab AT springs are 23287270

2016 1500 series Crew Cab has the 23287270 leaf spring set.

 

 

 

 

Not just the '16 Crew Cab.......my '16 Z71 Double Cab also has the new 23287270 spring set............no vibrations at any speed. Cushioning in the 40/20/40 bench seat of the '16 appears modified from the '14-'15 also

 

Tried that water in the bottle in the cup holder of the armrest test Youtube posts and the water surface does vibrate and the hinged console with crap inside appears to vibrate a bit on a highway with expansion strips but nothing else does! No vibrations felt in the wheel, pedals, or my ass sitting in the driver's seat. Test doesn't appear to be a reliable test of anything other than the mounting of the armrest.

Thanks for the info and pic. I am trying to track down if the spring rate changed between the part numbers.

Does your truck vibrate?

Does your truck vibrate?

It did. new ring and pinion, rear shocks and four rfbs to get it right... You can tell it still wants to vibrate at speed, but it's on good behavior this week. Plus the Bilstein 4600s seem to have calmed down the sensitivity to small bumps on the road.

      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

      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...
