Hi all, I'm new on here and looking for help on my recently acquired 2005 Legacy Spec B 3.0 manual.
This has a drain plug under the diff which is shown in the manual but behind that there is a sump with another drain plug on that. :-\
Should both of these plugs be removed to properly drain the gearbox oil?
Do they both have washers and if so do they really need to be replaced?
