Looking for rear end parts for 2004 Quad, I have replaced the position sensor and calibrated the rear steering.

GMC claims they don't make replace parts anymore? Can anyone advise if there is a aftermarket source for seals and other parts?

thanks

I'm pretty sure they don't make parts... It'll be tough but try searching craigslist and call around scrapyards for parts.. Probably your best bet.. Or buy another quadrasteer truck as a parts truck.

Some parts on the Quadrasteer system can be purchased new, albeit expensive. The rack housing is no longer available. You need to find a decent condition one used.

 

Best of luck.

Look at denalitrucks.com for Quadrasteer related info. They have everything you could ever need.

 

Do you know the fault/s in the system presently (ie: chassis codes)? I might be able to help you. Recently, my rack failed and I needed to replace the whole thing. Did a lot of research. Found what I could for new OEM parts and the rest I had to get used.

Are you kidding? Would I have been Pissed if I put the cash out for one of those back then when they were touting them as the next best thing and they won't even support them 10 years later.... I mean they ,may not have been popular but they do function as they are supposed to ....

 

 

Hope you find your parts....

You're absolutely right. The level of frustration that Quadrasteer owners have with GM is unreal. If you bring a QS truck to a GM dealer, they will likely put a new rear position sensor in without really knowing what the problem is. If that doesn't work, they call the GM hotline and GM tells them to pull the QS fuse and just disable it. If you're lucky, you'll have a shop nearby with a service department that is savvy enough to work with you on the repair and do what they can. That's a rarity though.

 

So you basically have to DIY the whole thing with good condition parts from recyclers and try to stockpile as many leftover OEM parts as you can. It's not terrible but GM should have allowed for a little more support on this system.

 

As I understand it, Delphi was trying to make a 2nd gen QS system and they had the prototype ready just as GM killed the idea altogether. Delphi's branch that worked on the QS project is now Newsteer or something like that. They won't respond if you ask questions about the system. They don't care.

 

if it wasn't for denalitrucks.com, I would have sold the truck when my QS died. Now that it's fixed the truck feels awesome. It's tough to go from a 4WS truck to 2WS. The difference isn't even comparable.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."
