Recommended Posts

Pads from manufacturing who make the brake pads for Gm  we’re replaced because of squealing at a crawl

@maximumspeed, I have the same problem (still). I found another post mentioning this issue that referenced a bulletin # (20-NA-020 - https://static.nhtsa.gov/odi/tsbs/2020/MC-10172288-9999.pdf). My dealership replaced all of my pads and the noise is still there. I asked my service department about it again and they told me that the "mixture used in the brake pads was changed with 2020's and they're still working on figuring out the noise issue". They also told me they'd replace the brakes again whenever the mixture gets figured out. I think it probably won't ever be figured out and I'll just wind up replacing the pads / rotors setup. Side note - I live off of gravel so not sure if that has anything to do with it but my last Chevrolet truck didn't make noise like this while I drove it on gravel.

I broke 30k and since I bought it new they have squealed.  Conway, AR dealership stated several times that they are working as designed no issues with them squealing.  Got to love it.  Showed them instructions from GM on what to do.  They have refused and stated it is working as designed.  Good luck on if they will address it.  Probably going to upgrade to PowerStops as I have NEVER had them squeal.

Dad had the same issue, dealer replaced the pads twice, the squeal always came back at low speeds.  Finally got frustrated, and even though still under warranty installed the wagner posi quiet (might have been centric thermo quiet pads)  Problem solved,  I know it sucks, but the noise was driving dad crazy.

Just so everyone knows I had a call from Gm about my brakes and they tell me that they won’t pay for another set of brakes as they have been replaced once then she tells me that they recommend new brakes every 12000 km lol my reply was WHAT

seriously who is this person. I will be calling tomorrow because the person that called me I’m sure has no ideal what the hell she’s talking about 

more to come stand by 😎

Ah yes, the awful squeal noise on my 2020 GMC Sierra Denali HD (2500) is familiar. I've had my pads replaced once and the squeal came back quickly. I am looking for an aftermarket option and prefer EBC brake pads and rotors, but they don't have any pads for the 2020+ HD trucks. I think that GM screwed this one up BIG TIME with the consumers, but what do they care, because vehicle demands are way to high and customer service has suffered. I was in shock when the dealership pad slapped my new truck with the service bulletin. At least the rotors should have been turned.

      Was wondering if anyone else is having issues with upgrading their OEM wheels?ive got a 2021 LT 2WD with 20” tires and wheels and wanted to change over to the High Country wheels. 
       
      keep hearing that they won’t fit? Anyone else aware of this issue? Something to do with the brake calipers or wheel liners???

      I purchased a 2021 Silverado with the towing package along with the extended towing mirrors.  I am hoping to replace them with some kind of power folding mirror as now the truck will not fit in my garage without manually folding in the drivers side mirror.  The dealer told me there is no fix and can not add any power mirror due to the computer in the 2021 Silverado.  Has anyone come up with a fix for this yet?  One would think that spending 62K this might be offered as an option  Thanks.

      Are you Looking to change your headlights and grille on your custom Silverado to the LED HID / signature curtain daytime running lights that High Country’s come with and the bow tie grille ?

       
      Here’s how I did this to my Custom Trailboss ... how to video.  Videos nothing special but it’ll give you the pics with notes /video clips that  I took so you can convert yours over if your wanting to .  Back when I did this conversion I couldn’t find anything online that really shows how you do this so hopefully this helps the next person do this .  Takes about 3-4 hours 
       
       
      cost is about $3k for all new oem parts .  I got my headlights , wire harness through Gen5DIY.com  $2400 and the bow tie grille $580 through gm parts warehouse.   Both are great companies I’d fully recommend that made the process really easy .
       
        I’ll list the part numbers too if you wanna research and look for some lower prices if wanna go with used parts or shop around if you wanna that route but don’t forget you’ll still need the headlight harness which is about $250 from Gen5DIY to make all the lights work properly .  After you sell your used Custom headlights and grille parts from the conversion you can get back about 1k dropping the cost involved about 2k with new parts.
       
      May ask why not just buy the LT trail boss ., well here’s why I did not .. when I researched this is what I found ., 
       
        My Red Custom trail boss came with the halogen lights and the LT Trailboss has the better looking lights that are LED  (not too bright though but have a good look to them still) but they are not HID LED which are way brighter unless you buy the midnight black edition trail boss or the high country which #1 I wanted the red trail boss not black , # 2 I wanted HID LED lights not just the LED lights , so I made my own custom set up for a small cost compared to getting a midnight edition Trailboss or high country 

       
      part numbers 
      LT Black Trailboss Grill with Z71 emblem
      84493318   New 2019-2021 Silverado 1500 High Country HID LED head light assembly  Drivers side LH.      : 84621852 Passenger side RH  : 84621853

      Used “like new” condition off my 19’ Custom Trailboss .  Truck literally has 8,000 miles on it still so these parts look like the day they did it came off the dealer lot.     Asking $450 obo +shipping which I believe is about $65 to most places In the US.                                   I changed my headlights and grille out recently after doing a headlight conversion so I have my grille and headlights that came from the factory for sale now .

      I am new to this http://www.gm-trucks.com/forums/profile/181793-grubbworm/ , but not new to truck forums. I recently won a 2004 GMC Sierra 2500HD 4X4 Extended Cab 6.0 in a raffle. I won it at the local Cobb EMC 2017 Annual Membership Meeting. My wife and I already own a 1985 Ford F-150 4X2 truck that we purchased when we got married. We have done quite a few upgrades, repairs, and restorations to it throughout the years. I have a Photobucket account where I have some pictures of the work that we have done to our Ford, http://s774.photobucket.com/user/Grubbworm_photos/library/My%201985%20Ford%20F150%204x2?sort=2&page=1 . I look forward to working on this truck as well. I think we will make this GMC our new Go-To truck for Fishing, Camping, Hauling, and Towing. I have started a new photo library for the GMC as well and will be adding to it as any work or upgrades progress, http://s774.photobucket.com/user/Grubbworm_photos/library/My%202004%20GMC%20Sierra%202500HD%204X4?sort=3&page=1 . I enjoy doing 99% of my own automotive mechanical work, and some limited bodywork as well. Being that this was a work truck with 160,000+ miles on it when we acquired it, I have already come across a few issues. Even though it appeared very well maintained, the first issue was with the burnt out DRL’s. I replaced them with some new sockets and 7114 LED’s. There are what appear to be stress cracks around the front stake pockets on the bed. That will be a welding and body project for a later date. I have also wired my Tekonsha Prodigy P3 Brake Controller in. The next issue happened on Halloween evening, the Check Engine Light came on. Today I went to the local O’Reilly Auto Parts, where they pulled a P0327 – Knock Sensor Bank 1 code. After some forum reading and some YouTube’s, I pulled the plug on some OEM GM parts on Amazon. It appears that I will be doing another repair in the upcoming future (weather permitting). I am also considering doing the headlight lens cleaning and polish. I recently did this on my wife’s 2005 Mazda 6 and turned out fantastic. I highly recommend the Sylvania Headlight lens cleaning kit. The cost was $20 and 1-2 hours labor time. I also put the before and after pictures in Photobucket of this. I look forward to sharing pictures of the repairs and upgrades that we do to this truck as time goes on.
