Possible Driveline Vibration?
Okay so I will be taking my 06 Gt in on monday for what feels like out of balance tires. The vibration is very subtle but enough to know that it is there.
However, last night I noticed something. On the highway doing 100KM HR steady the vibration is noticable but very lightly, but if I a crusing steady at 100KM and press the gas down just enough to increase my speed without downshifting into 3rd I can feel the vibration incread steadily unitl I hit 115 - 120KMs. So here is my question: could the source of this vibration be something other than the wheels? Also, if it was something other than the wheels (i,e dirveline, motormounts etc..) shouldn't it be preset at any speed? The car rides absolutely smooth at lower speeds. Starts vibrating at 80KM hr.
