Hi Everybody,

I am just wondering if you could give me some hints how to service rear differential on 740 GLE 88.
I have a small oil leak by the rear wheel bearing.
What should I do?
Do I have to replace inner and outer oil seals?
How much trouble is to take off a wheel bearing to replace outer oil seal?
Can I get by on replacing only inner oil seal?
What kind of oil I should use?
The volvo dealer is suggesting volvo oil which is much thinner then old oil. What should I do?

Thank you in advance for your help!
