I'm not sure where the differential adjuster is so this is assuming it's sealing something inside of where the drive flange oil seal sits. Excuse the ignorance, but wouldn't the oil seal keep gear oil from leaking out the drive flange area from behind the plastic cap? Is there something else that I should have replaced while "in there".

Thanks!
