Are you sure for what you said? I've already tried to rotate the diff but doing that the brake pulley and the diff pulley are no more aligned.
If you see the rear differential pulley is left-position by approximately 1mm or more and so, rotating it will move too much to the right...
However the belt should not come out because the composite right-bulkhead will stop it (the belts will bump to the rear downward multiflex connection)
