Outer Limits 4x4 Board

hey
rear diff seems to be leaking from where the drive shaft enters it.
which seal would have let go and do u acess it from the diff centre?

That would be the pinion seal.
No need to remove diff centre from housing.
Remove rear shaft.
Remove flange from diff. (not as easy as it sounds)
Replace seal.
Reassemble.

Jas.

also, check that the pinion isn't loose.
