differential leak and black lug nuts
My car is a 2014 mustang GT
I took my car to ford for a oil change, they said they found differential leak but they wanted 100 bucks just to figure out why it's leaking.
Before I spend this 100 bucks, is it a cheap fix? Or am I better off taking it to some where else?
My car is about 50k miles on her, I don't want to take it somewhere else and they make it worse then it is.
Also I bought some 19" black glossy wheels. They were off from a 2016 mustang GT.
Can I use 2016 black lug nuts? Or do I have to get 2014 black lug nuts? I don't have the 2016 black lug nuts, but since these are a 2016 black wheels, might as well right?
