Hello all, I found this site by googling F-150 squealing upon acceleration and have read through several of the threads pertaining to this. Unfortunately i wasn't able to find any likely explanation beyond a water pump seal, a pulley, the transmission and the butterfly valve on the intake. I pulled up the tsb's and regarding the squealing of the clutch system upon acceleration for the 2012 F150 and the 201 mustang and showed it to the service manager this morning during my visit. The manager couldn't hear the squeal but the "lead transmission and exhaust guy" at the dealership did. He thinks it is the drain port on the exhaust system about halfway up the exhaust of the truck (we all have it). My problem was labelled a characteristic and not a defect. I feel as though i should not have this given the price tag on these trucks. I have since reported it directly to ford and will post their response. As for now, when the engine is under a load (via power break or acceleration) i get a very high pitch squealing between 1K and 2.5k rpms. Please let me know if anyone has had any success in getting this resolved!


Thanks you all and sorry it took a "squeaky" wheel to get the grease (i.e. get me here!)

Thanks again,
Will
