hi i'm diong a n\a auto to turbo 5-sped swap. i removed the n\a diff and started to replace it with the turbo 3.90 diff. my brand new oil started to leak out the pinion seal as i was putting it in. how difficult is it to to replace the pinion seal without the special service tools and should it be in car or out?
thanks ahead of time.
