I think that question came up before. With the outer seals you can’t tell when your inner seals are bad because all the gear oil will be trapped inside the tubes.
So these things on the outside of the axle shafts are called oil slingers! Why are the on the outside? I am considering since I have to pull my shafts to change an inner seal that is leaking to add outer seals I would like to see everyone's thoughts on the outer seals????
That is a good point! just cannot figure out how I killed a seal on a 2017 Jk with only 15K miles. I was guessing dirt or mud got in there.
Isn't it under warranty ?
