It's refreshing to hear somone say they are not too bad, gives me a bit of hope! I have read so much about failing output shaft seals, or diffs whinning, that I have become almost convinced my diff will fail fairly soon!
I read in the latest 'Practical Classics' that the Editor has just had to swap his diff on his XJ40 and looking on the internet it seems to be a really common issue.
I just know it is a job I would struggle to do myself, so I want to prevent problems if at all possible.
Do you think the 80/140w oil would lessen the likelyhood of seal or diff failure?
