I changed mine both to Amsoil 75-90 gear lube.  At 65,000 miles the back looked ok but the front look bad.... thick...  I glad i did both.

I changed the rear at 5K after my first 500 miles of towing.  every 25K for the rear, every 50K for the front.  Mobil 1 front and rear.

I changed both front and rear at 12k. Filled back up with the Series 2000 75w-90 Amsoil synthetic. The magnet had little fuzz on it but nothing bad. I will change it back out in both at 50k.  :thumb:

      2027 GMC Sierra: Official Discussion

      By KARNUT · Posted

      We live in a world where the average person expects more. People say wages and our needs are farther apart. My first new home had 3 bedrooms and one bedroom. My first car and truck had what would be considered a stripped or work vehicle. In my neighborhood back then there were more homes like that and cars too. Middle managers and second home buyers worked their way up to the fancy houses and cars. Car loans were 3 years. GM had different models of cars for different income levels. The cars were pretty much the same size if you wanted a big vehicle. The nameplate designated the opulence. Chevy, Pontiac, Buick, Oldsmobile and Cadillac.  To be fair some of the cost is government mandated. We can’t blame them for giving us what people will pay for. Careful advertising steering people towards more profitable SUVs and trucks. As I learned recently a minivan is a cheaper more efficient form of transportation. Certainly easier to live with. Somebody realized the profit margin wasn’t as big and gave it a soccer mom label. So it lost its coolness. They’re making it the masses are buying it. You hit your hand with a hammer you can’t blame the hammer.

      Electrical /Immobilizer Data- Battery Voltage (V) Test malfunction

      By Aussie2500HD · Posted

      Hi All, I’m In need of advice regarding a scan result on my 2023 Silverado HD.  The Sensor Supply voltage relay states ON But…. the following 3 tests show Malfunction. Sensor supply voltage relay control circuit HIGH voltage Test status- Malfunction Sensor supply voltage relay control circuit LOW voltage Test status- Malfunction Sensor supply voltage relay control circuit OPEN test status - Malfunction. No DTC codes are stored. No DIC Lights. Remote Key Fob has been giving a few issues, namely Vehicle will not respond to an Open/Lock command from the key fob. New batteries installed to FOB made no difference, plus on one occasion recently the vehicle unlocked using the Fob, the vehicle started normally via the push button, then a random warning came up on the DIC stating the Remote Key was not found, all this while the key was located next to the central cup holders. Does anyone have any input or advice regarding this scenario? TIA

      I agree, simplicity and reliability matter more as vehicles get more complicated. A V8 work truck option with fewer electronic features and a stronger warranty would definitely appeal to a lot of buyers who use their trucks for real work. Customizing it with trusted outfitters is often the best way to get exactly what you need

      2026 Sierra 1500 Denali - Sound upgrade?

      By artistemorbidity · Posted

      I’ve heard similar complaints from newer vehicles where the factory “premium” systems don’t always live up to expectations. A good installer should be able to improve the sound without turning it into a bass-heavy setup. I’d look into upgrading the front speakers, adding a quality DSP amplifier, and possibly improving sound deadening first—those changes usually make a much bigger difference than just adding a subwoofer. Hopefully someone local can recommend a reputable installer in the Las Vegas/St. George area.
