Old Torsen diff centre out and sold. Came out in very good condition, magnetic drain plug was spotless and no signs of wear.
OS Giken super lock installed and lock wired. I used a bearing heater to install new bearings, so much easier than pressing them on, new seals and the special Subaru diff cover gasket with the baffle in front of the breather. All wipe patterns and specs checked out. 1.3L of OS-250R oil. Short test drive, you don’t even know it’s there!
