Over the last week I have noticed a heavy vibration that feels like it is coming from the center of the vehicle when I am in gear and sitting still. I do not even know where to begin. Any ideas??

Engine mounts? Or is it bogging down?

 

A shot in the dark but if you’re in gear and foot on brake it could be the rear prop shaft. Or it’s bearing/bush. particularly the bush tends to go eventually.
