I have had a rattle/grinding on hard acceleration since new. 2WD only. My dealer has finally concluded it's a 4WD issue. But that is as far as they can get. They say they check all the vacuum lines. They can't find the problem. They are back to looking for codes.
With all that is going on, I don't want my truck in the shop. I think it's best if I just fix it myself.
My dealer says the 2019 don't have the IWE check valve or solenoid issue. Is that true?
Any ideas where to look?
