I have a 2000 GMC Sierra 2500 HD, I think I bought ABS hubs for a four-wheel drive mine is two wheel drive I've included pictures of the one I bought and the original I took out and I'm wondering if I can replace it with the ones that have a hole in the middle for a spline to go through

Wrong forum, and your pictures didn't load. But NO you cannot use 4wd hubs on a 2wd. The 4wd hubs use the axle shaft and nut to hold them together. The 2wd hubs have a piece going through them to hold them together. The 4wd hubs WILL separate and FAIL if you try to use them on your 2wd.

There isn't a "2500HD" in the 2000 model year.  There was just a 2500 in the new body style, and there was 2500 in the Classic (88-98) body style.

 

Which truck do you have exactly?  If its the 1999-2000 year range new body 2500, you CAN NOT use a 4x4 wheel bearing.  GM revised the hubs on these trucks many years ago, and for the 1999-2000 2500 4wd and 2001-2007 year range on 2500, 2500HD and 3500, the current OEM service hub is the same on 2wd and 4wd.

 

The 1999-2000 2500 non HD you MUST use a 2WD specific hub as the flange to bearing offset is different.  The OE hub is discontinued.  Timken # is  HA590352 and is still available.  Read below from the bulletin:

 

#08-03-08-003A: Wheel Hub Changes - Gen III vs. Gen II - (Mar 2, 2009)

The only hub that is not back serviceable is P/N 15719007 (not pictured) for 1999-2000 C25 applications due to a different hub flange to bearing flange offset.

Important: Only the new part numbers referenced in this bulletin are interchangeable between the 4x2 and 4x4 applications with the exception of P/N 15719007 (Not Shown). Under no circumstances should any other 4x4 hub be used in a 4x2 application.

You need to scan for codes to see what is turning on the light.  Could be an EBCM fault.

Still the wrong forum. This forum is for 2019 thru 2023 Silverado and Sierra.

I went to O'Reilly's and AutoZone to scan for codes and there's no codes that come up, I also replaced the brake master cylinder, flushed out the brake lines, had front end alignment done

If their scanners will only read P codes, then you won't see any codes you need to see still.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
