I just recently rebuilt my dana 44 and I was wondering if I needed inner axle seals? When I took it apart there was no seals so I assumed when rebuilding it I didn't need them. But after looking im not sure how my wheel bearings will get oiled because the fill plug is below the axle tube and once I filled it up, I took out the axle shafts and its not leaking oil. Should I install inner seals and grease the wheel bearings? Or will driving it slosh the liquid around enough to oil the bearings?
