hello all, the tail-pipe of the exhaust on my terrano 2.7 td snapped off from the centre box recently. I was looking at this and noticed its damaged a hose underneath it which runs from the centre of the rear axle to the propshaft (?I may have got the part names wrong i'm no expert and have trouble making head or tail of the workshop manual). Does anyone know what hose this is, what its for and what problems it being damaged may cause? Ive looked in the workshop manual and on car parts websites and cant find anything about it anywhere. Thanks, Rob S
