I am new to the ford performance world. I recently purchased a 08 Gt 5 speed. When the car gets up to operating temperature, it will make a groaning/clunking sound while I turn. What is going on ! I’m thinking drive shat.
Not sure what it is. I hear the drive shafts in these cars are two piece and garbage.
You are refering to rear end gear oil, right? Yea, i used royal purple in mine. It comes with the friction modifier in it. Ford stuff is good to from what i read. Just make sure friction modifier is in it or you add it as recommended.It doesn’t make the noise at idle or driving straight. It only makes it when turning. I was told to change gear oil to a ford oil. It’s a 5 speed.
50k. Two wheel marks on a burn out.
A proper scientific study requires multiple repetitions.
