2017 Silverado double cab 4x4, I changed the rear gears so I can only drive in 2wd until I get the front ones changed. it has a 9 inch Mcgaughy’s lift on it. am having a grinding noise and it sounds like it’s coming from under the front area. It happens when I am pressing the gas and staying at the same speed. Say If I am going 35 and I am lightly pressing the pedal to stay around that speed I hear a loud grinding and vibration. If I let off the gas it stops, if I press the gas harder it stops.
I really need some help with this. I can’t figure out what the problem is.
