Frame Rust

I have a 2014 GMC Sierra Carbon 22 with 81K miles.  Love the truck, hate the frame rust!  It's really sad to see GM used an oil based wax coating which lasts about 1 year in cold climates and allows rust to start.  The entire frame has rust and these pictures only represent a small amount of the total rust.  I remember reading an article by a GM engineer on the 2014 design team and stating this was the most rust resistant truck GM ever designed.  The article helped me decide to buy this truck - https://media.gm.com/media/us/en/gm/news.detail.html/content/Pages/news/us/en/2013/Sep/0905-silverado.html   I have a 2009 Vibe, a 2007 Saturn Vue, a 2011 Impala and a 2017 Impala with more miles in the same climate and none of them look this bad.  I was planning on holding the truck 10 to 15 years as a daily driver and thinking of buying a 2019 C7 Vette this month but it looks like I'll have to put that on hold while I evaluate selling the truck before the rust get's too bad or to the point of structural damage.  My friend bought a 2014 Tundra at the same time I bought this truck, his frame looks great and he has 160K Miles on it!  

 

Come on GM, you can do better!  Powder coat or bond these frames with better rust protection than the cheapo oily wax that only lasts a year.  Even the 2020 trucks use the same wax coating...

That's just bare metal exposed, it's surface rust nothing major. You can clean that up in a few hours, I wouldn't trade the truck over it.

Some good info in this thread.  I cleaned my (much lighter) surface rust with a paint stripper wheel and recoated with the original daubert spray.  Yours looks scaly.  It'll need to be resurfaced with some aggressive abrasives, hopefully there will be some metal left over.

The frame on my 07’ 4Runner with 105,000 miles on it that has spent its entire life in brutal Chicago climate doesn’t look that bad.  GM sourcing cheap Chinese grade steel these days?

The point is you should not have to redo your frame after 1-2 years on the road. This stuff is garbage and a cheap work around for GM to not supply a true coating. They are cutting wayyy too many corners lately and the quality of their products is noticeably decreasing. The only thing you need to know is that even with a rusty frame, the rest of the truck will be long dead before you have to worry about the structural safety. You wont get 15 years out of these trucks unless you grandpa it, garage park it, and never drive in rain or snow. We didn't get 15 years out of the GMT800's and they were twice the quality of a K2.

      Broke Down on the Mountain

      By Gangly · Posted

      I was in Utah this week attempting a bow hunt in the Wasatch mountains with friends.  On the evening of the first hunt, making my way across a ridge to a friends camp, the upper control arm on the driver's side separated, the CV axle got trashed, and the wheel was dang near at a 45 degree angle to the ground.  I was able to get it towed off the mountain and into town about 3:00 am, and spent the remainder of the night in an O'Reilly's parking lot.  Luckily, there was a Chevrolet dealership not to far away so I was able to get to the dealership and pick up a new CV and UCA.  It would have been a few days before they could have gotten to the truck and I brought tools with me on hunt since it was a two day drive to get there, so I did the repairs myself in the O'Reilly's parking lot.      What's interesting is that the UCA ball joint didn't break, it just popped out of the bottom of the UCA.  There was VERY LITTLE evidence of grease on the ball joint or in the socket, and you could see where the ball joint had warbled out part of the socket over time.  I guess that's what happens over 186K miles of use :)   Big Kudos to O'Reilly's for letting me work on the truck in their parking lot.  However, they made a $150+ off of me from the purchase of various tools, so I guess it was in their best interest anyways :)   Getting towed off the mountain.   UCA Ball Joint Socket   Trashed CV   Suspension disconnected and UCA and CV Removed   New UCA and CV installed with the suspension buttoned up.

      What did you do to your "other" car (aka musclecar) today

      My family still laughs at me when they see me drive up in the minivan. Same with less than a V-8 truck. It helps that I have choices. I don’t think I could only have a minivan as the one and only vehicle as much as I like it. And I wouldn’t pass up a good buy on an older V-8 reg cab GM truck. Could you live Raven as the only ride?

      PF63 Oil Filters Going Away?

      By mrjulian416 · Posted

      Oil and filter threads are always a good time.  Especially when the BITOG discussion forums are cited as a definitive, technical source.    Countless single-data-point examples of why something is the best ever, or will destroy your engine... "they changed the shade of blue on the filter can, use at your own risk!"... "I've heard they changed the design to only have 64 pleats, total junk!"... "They're hidin' the NOACK data from us!  I wouldn't use that stuff in a cement kiln!".... "There was a guy who cut open Filter X (with a sawzall) and the anti-drainback valve was orange!  It used to be black!  Chinese junk!"   Good stuff.

      Installed Bilstein 5100's on my 2024 2500HD - Worth it - VIDEO + GIVEAWAY Inside

      By fondupot · Posted

      I finally bit the bullet and installed a set of Bilstein 5100's on my 2024 Silverado 2500HD. My truck had about 75,000 miles and I've always felt the factory shocks were less than forgiving. So Bilstein 5100's are the most common go-to replacements. I personally have installed them on many trucks....2002 Silverado 1500, 2014 Silverado 1500, 2017 Chevy Colorado, 2019 GMC Canyon, 2022 Silverado 1500...now my 2024 Silverado 2500. I will eventually put them on my 2021 GMC Yukon as well. Great all around shocks.    Below is my video tutorial installing them on my 2500. As a bonus, for recently hitting 20,000 subscribers on my YouTube channel, I teamed up with Nick Scovel Jr at Scovel Motorsports to create a giveaway. Details are in the video description.

      What did you do to your "other" car (aka musclecar) today

      By Grumpy Bear · Posted

      Raven    About 2 more weeks and this Mirage will be two years old and already packing 54K miles. The CVT has settled in and is outperforming my expectations. The engine in quite, smoot for a three pot and very economical to fuel. Life time result to date is a stunning 52.44 mpg with a median tank of 52.74 mpg. Given the number of miles I drive and the cost of fuel lately this buy has turned out to be quite the winner in this stable.       She is also quite the teacher. Nice thing about a car that gets this type of milage is that you see the results of minor changes with the change instead of having to average a months worth of gas tickets to filter out the tank to tank scatter. Those lesson apply to everything in the fleet and everything I've done to the pack works with this one as well.   EPA numbers for this car:     This example is running 42% over the government values!!!!  😱    I am really enjoying this car. Can't even hear the laughing of those that thought this a 'dumb/disappointing buy".
