I have been noticing over the past month or so that my Manual BA is getting some driveline shunt when I lift off the throttle, change down gears or driving slow in a carpark. I have been trying to drive around it but it sometimes catches me off guard . What causes this? Can it cause damage? and Can it be fixed?

Thanks

Diff is shagged...will cost quite a few $$$ to get fixed.
Mine is the same, even though I just installed it a few months ago and it was suspposedly a reco'd one.
