I have a 2012 GT
6MT with 3.31 gears. I recently took it in to my local dealership (Fritt's Ford Riverside, CA) as my diff was leaking and spotting my driveway again. It looked as if the vent on the driver's side was leaking soaking everything once again. I do admit I drive the car as I 'thought' it was meant to be driven. Apparently, after hauling *** the fluid heats up and spews fluid out of the driver's side vent. I noticed a leak from the diff last summer, my suspension, wheels, and tires were stock, the dealership replaced the driver's side vent and fluid and the car was back to normal. Shortly after, I installed Eibach Pro Street Coilovers, RTR wheels, and Toyo Proxes T1 Sports. My car was fine until recently when I noticed the infamous leak again. The dealer checked out my car and they just informed me that Ford denied a warranty repair as I have lowering springs and that changed the pinion angle causing the fluid to heat up and spew out of the vent. That does sound somewhat true but to what extent? There's thousands of folks out there with coilovers or lowering springs that I'm sure have had the same problem but weren't denied a warranty repair. What have you guys done to fix the leak issue? Replace the vent with a turkey baster vent? Your comments, suggestions, help, is greatly appreciated.
