2013 GT already in the Shop
So, I installed my lower control arms last week, after I had them installed I went to a local mechanic jut to have him torque the bolts down. As he was under there, I noticed some oil leaking from the differential, so I had to take it to Ford today. I don't know what the problem is, maybe the pinion seal, I don't know. But whatever it is, it shouldn't be having any issues with 3000 miles on it.
