Time is a factor. And ford doesn't pay to tow your car from dealer to dealer to shop for a tech that isn't afraid of a fwd turbo fiesta that he's never heard of...
Just pointing out... If they see something stupid like a BOV spacer, and they deny repairs based on that, what are you going to do? Pay a tow truck $80 to tow it 20miles, for another ford tech to look at your VIN history and say, "they didn't touch it, I'm not gonna touch it", then what? Tow it again? All over a $10 seal and 45min of labor?
I think they SHOULD fix this issue. Just pointing out, playing it safe with these tech's that at Determined not to get stuck working on this unicorn is a good idea. And I'm not just talking about this axle seal, I mean anything. If your AC stops working, you may wanna put your stock lug nuts back on, because they may blame them, lol.
