IMHO, It is a harmoic vibration that is coming through the floorboard... either a bushing that is less pliable at colder temperatures... or a rub. I am not sure which. My money is on stiff rubber bushings. The vibration of the drivetrain is getting passed right into the cabin due the the bushings being cold and stiff.
Anyone try the Whiteline Rear Differential Bushing Kit? I just went to stage 2 from TDC Stage 1 this past weekend and the vibration during accelleration is alot worse now
wonder how hard this is to install? Can't be too bad.
