Leaking 9" Diff solved?

I've tried everything I could think of to seal this 9" diff ever since I've had it. I went to replace the pinion seal and found a lot of pitting around the pinion flange where the old seal sealed it, so I replaced the pinion along with a new seal, hopefully problem finally solved.


Here it is installed.



Here it is mounted, so far no spots of oil on the floor

That would have been a good place for a Speedi-Sleeve.

Almost looks like there was one on there already.

Make certain an oil slinger (shield) is installed behind the seal. It helps reduce oil splash onto the seal.
