Its leaking from the nearside diff oil seal.
My mechanic said he could change the seal, but saabstyle in cardiff say that because the shaft has up and down play in it that the sleeve inside the gearbox needs refurbishing.
Anyone else been through this, think saabstyle are likely to be correct, or just tried changing the seal?
I'm thinking of changing the gearbox oil on my 2001 TiD soon (108K miles). Is necessary to change the oil a total of three times? What effect could it have if the system was drained and then refilled once? Sorry if this is a dumb question with a really obvious answer
