Pinion Seals


Hi guys/gals. Doog here from chch NZ. Happy New Year to you all. Now, I'm having an ongoing problem with my pinion seals front and rear diffs. I've replaced them a couple of times. I've had the casings checked out and aparently they are not that worn. Does anyone else have pinion seals that need changing every 6 months or so? I do keep the breather tubes unblocked and regularly change the diff oil after getting water in it.

Change the yolks that the prop shaft bolts to. They wear around where the seal touches.
