The other day I noticed both of my pinion seals are leaking on my diffs. I called the dealer today to check the price, they needed to know if I needed the flanged or non flange seal. I wasn't sure so I asked if I gave them my vin if they could tell me, he said no.

So do I need a flanged or non flange seal?

I have a 2001 sahara with a 30 up front and a 44 in the rear.

Also, what would be everyones thoughts on me (a novice) replacing the seals? Is it easy enough?

They are cake...but I've done far to many pinion seals.

Remove Drive shaft.
Mark pinion nut with pinion
Remove pinion nut
Remove yoke....(may have to tap it off with a hammer)
Use a seal puller to remove old seal. ( can use a flat head screw driver to remove but be VERY careful to not scratch the inside of the pinion where the seal sits.)
Replace seal with new. (can use a block of wood to tap it in slowly with a if you don't have rubber mallet.)
Put pinion yoke back on.
Put pinion nut back on and torque to spec.
Put drive shaft back on.
Done.
