Hey All
Its been a decade since I’ve owned a General Motors Truck. After having horrendous issues with 2 other domestic brands, I’m back with a 2021 Sierra 2500 6.6 Gas HD. Looking forward to this new journey.
Love everything about this truck so far!!!
I hear this in my 2500HD. If I sit in the driveway idling and lightly increase rpm and then take my foot of the pedal I can hear a whsssssssssssst noise. Mine seems to originating from the steering column, but that is pretty close to where you are describing it. I've never thought to be enough of an issue to bring it in, from what I can tell everything is tight and there are no vacuum leaks (my truck doesn't have vaccuum assisted brakes like the 1/2 tons).
You guys are saying you can't fit a 16" rim on these trucks??? I have a 16" steel spare on for my 2500HD. Do the 1/2 ton trucks come with a larger diamater spare wheel?
