Hello, Jim from MD here. Found this forum when searching for the dreaded “grinding noise coming from under truck”, in my case, my 2018 Platinum. Took it in for the service today and they just capped the vacuum lines. Seems a pretty half-a** fix from Ford. If the vacuum lines were important enough to be on the truck, seems to me they’re important enough not to be isolated like that. Thanks for accepting me to the group.

 

Welcome to the site Jim!

 

Welcome to the forum, Jim.

 

Glad to see you. Crazy experience at dealer...wow.

 

Thanks guys. I just hope the fix doesn’t affect the performance. The TSB says it won’t...

 

Welcome.
TSB suggests it's a common problem..
