Morning, Just wondering what the symptoms would be for a propshaft thats wearing out? Basically I am noticing a small vibration and a droning noise when I put my foot down at low revs in any gear - seems to be the most apparent in 5th. The noise and vibration is gradually getting louder / worse. In lower gears it makes more of a "knocking" sound. - I will try and take a video so you can hear what it sounds like. I have had wheel bearings and CV joints go in the past, this sound is completely different. When I purchased the car I changed the gearbox and diff oils, the levels are fine.
