5 weeks at the dealership now!!
My 2018 Raptor has been at the Ford Dealership for 5 weeks now. It still makes a grinding noise in 2WD, 3rd gear, 5200 rpm. Today is Friday and the service rep told me today that the area (northern California) FSC will be stopping in today or early next week to try and figure out what is wrong. On June 19, 2018, A friend of mine sent me an OASIS message that goes out to the dealerships. The OASIS message discussed - "Intermittent Grinding Noise from Integrated Wheel Ends (IWE) while driving in two wheel drive. This may be caused by an intermittent leak in the check valve. Before completing any normal diagnosis suspect that the check valve is the root cause of the issue. If the check valve has been ruled out as the root cause for the issue refer to work shop manual 308-07 and follow normal diagnosis."
To the best of my knowledge, the dealership has replaced everything in the vacuum system. If the area FSC doesn't find out something very soon, what recommendations do you have??? 5 Weeks is excessive. Thanks!
