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?
