Morning gents and ladies new to the site hoping someone can help me out with some advice. 08 XF 2.7 diesel jaguar have told me I have a drive shaft diff seal leaking and play in the bearing, the parts aren't made any more so need a new differential at a cost of nearly £3500!!!!!!!!! Has anyone on here had this sort of problem before and have you been able to over come it, I've been thinking about getting a second hand diff, will the diff off a newer model fit? Again any help would be appreciated.
