Disappointed,

Talk about timing! I'm witnessing this same exact same thing right now on a Ford truck forum. Two people have given good advice, but the OP has gone down a rabbit hole based on all of the bad advice that came later.

(Shaking head....)
Must be the OSB truck forum I am on there and I don't even own one, but I spent 15 years in a Ford dealership working on them and have 40 years' experience as a mechanic. This crap just drives me nuts, no one wants to invest in the time to learn how to fix anything. Shortly the only people that will have their own transportation will be rich people and mechanics, everybody else can ride the bus. End of rant.
