Hi guys, last year ai bought a 83 6.9 Diesel Econoline motorhome. From the first day i have a (not very loud) wining noise from behind when accelerating, so i opened te differential cover and found shimmering metal shadings in the differential fluid.
i have ordered this set from rockauto: https://www.rockauto.com/de/moreinfo...=1116526&jsn=1

is that all what i need or do i need anything else?

What do you think, could causue the the metal shadings? shims, bearings? The ring is looking very nice. The car has "only" 98k miles and is running very well. The number of my differential is 605114-9 (Dana 70U)
Thank you in advance!
