Did u figure it out?

Not yet.  This weekend has been extremely busy, so I have not been able to trouble shoot.  I am hoping for some time this week and next weekend.

Nope, all US units....  My boss does a TON of driving for work, and replaces his truck every 5-7 years, as his mileage is quite high.  The body and interior are immaculate.  The engine does have a lit

Has anyone had luck with the dealer addressing this issue? Just noticed this on my 2018 as well as a squeaky/creaky brake pedal (the creak seems to be coming from up higher near the brake booster).

 

I was just going to live with the annoying creaky brake pedal, but after the squeaking started I think the both of them may warrant a visit to the dealer.

 

I found someone on youtube (posted below) that posted a video about the same issue and while reading through the comments he stated that he eventually got the dealer to replace some exhaust components which solved the issue completely.

 

It’s unfortunate these two issues happen often (Almost every time you accelerate or brake) and become highly irritating. My truck is still under warranty thankfully. Am I being too critical or would this stuff bother you guys also and deserve a trip to the dealer?

Anybody have any luck? I've been fighting this for a couple years. At least on mine is definitely not the flapper valve because I cut it out when I put the new muffler on. Mine gets louder the higher the rpms.

I have a 2014 Silverado LTZ (very high milage - 219,000)  Runs great and still has some power left under the hood.  For the most part, it is in great shape.  It have a strange noise when acceleration or getting up to about 3 or 4 thousand RPM.  It only does it under load, so it is hard to find where the noise is coming from.  In the attached video, it takes place at 12-18s and then again at 40-46s.  It is hard to hear because of the wind noise, but I can't figure out how to isolate the noise any better.  If anyone has any ideas, I would sure appreciate the input.  The water pump was just replaced, and so was the alternator, along with the tensioner pulley.  I admit my limited knowledge under the hood, but I am willing to learn and fix it, if I can.

Hey I'm currently having the same issue with my 2015 Tahoe and can't figure it out I was thinking it may be the vacuum pump pulley but it only makes the chirping noise while in gear and accelerating I've replaced the tensioner,  that was my first guess but still not it, if you had it figured out and could save me the headache and time and money guessing and replacing parts that would be greatly appreciated

I had this same chirping. Just finished a new camshaft and DOD/AFM delete. No more chirping. 

 

There's a possibility the failed lifter was hitting the lobe of the camshaft (mine had a bent pushrod on the failed lifter) and this is why I chose to upgrade my camshaft while fixing the lifter with the DOD delete.

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Different requirements for oil filters?

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
