I haven’t been able to find any instructions on how to change the rear oil axle seals on my 2008 S-type 4.2. I have dropped the rear end for a refurbishment because the Canadian winter salt causes premature death. I don’t want to cause any damage so some help with oil seal change would be appreciated.
There is a Service or Workshop Manual available on CD-ROM from the dealers and other parts vendors on ebay etc.
There are drawings of the special tools and procedure steps. They don’t show a seal puller, but it looks like a weapon the Vikings would use, and you can get that at any auto parts store.
Here is the text.
