Deffo, I added a vibratecnics g/box mount and the rumbling I got through the cars was shocking.
O/P, take a look n see if the bolts holding the mount to the diff aren't fouling the ARB, it's a common problem. I ended up machining a new end plate for my mount that accommodated countersunk bolts, it's still close but it doesn't touch any more.
