Quick money saving fix on this 2019 F150 4x4. Came with squeeling and griding sounds coming from the front wheels, they took me for a quick ride and they thought it was the wheel bearings going out, and so did I, which would've costed them over $500 just for parts. But with a quick look and wiggle of the wheels that didnt seem to be it, so a quick search i found it could be the 4x4 vacuum system. I checked in the old check valve and it was full of orange dust. The actuator cap pops right off and the filter was also gross and full of dust. Cost the customer about 65 bucks for the check valve and the vacuum actuator and that was exactly there problem. After replacement and a test drive there was not a single sound coming from the wheels and the 4x4 works just fine.
