I have been hearing and feeling a bit of a sound that I am trying to pin point.
heres the setup.
ford 9" rear end.
4 link rear suspension.
Heres whats happening.
I will be cruising along(80-90kph) and get to a hill or a stretch before a reduced speed so I will coast a bit and that's when I hear a grinding-ish vibration and I can feel it too. Press on the gas and it goes away, let off and its back. Get below 70kph and its goes away. From trying to read things out form other posts and searching on the net I think it may be the u joints or a u joint starting to complain a little. . . has this happened to anyone and what was the fix for you?
