Regarding 2013-2018 F-150 vacuum system trying to engage the awd system resulting in noise up front sounds like dragging metal. 2018 Ford F-150 with the grinding noise out of the front hubs. Had this going on for 1 1/2yrs & been in the shop 2-3 times with recurring every time. Found a youtube that referenced a technical service bulletin. I took the TSB to the dealership service tech and here’s what’s on the invoice. . Confirmed customer concern, found there was a grinding racheting noise coming from the front end of the vehicle when driving in 2wd, found TSB 22-2019 for this concern following the TSB found the vehicle was equipped with auto 4wd, TSB stated to remove the vacuum supply line to the iwe solenoid and install 2 vacuum caps in their place. This is at Ford’s direction. Disable the system so that 2wd no longer active. It’s awd all the time. Still can shift into 4wd. Tech says this issue is so prevalent that that’s Ford’s answer. . Unacceptable. Disable the 2wd drive because they can’t work the problem.
