A leak on the outboard axle seal on the jeep's rear axle (D44) is a small thorn to tend. I've changed seals a couple times - the leak persists.
This last seal's install I siliconed the seal's outer surface (and cleaned surfaces as appropriate). I'm fairly certain that the leakage is not from the seal to axle tube interface but rather from the sealing surface with the axle.
Are "heavy duty" seals available? I don't recall the axle's sealing surface to be worn/rough - but it might well be. In that case, what repair options exist - does the axle get replaced or can the sealing surface be repaired?
I don't have reason to believe the outboard wheel bearing is at fault.
