Hi all again haha,

Getting ready to put new tire on the L355 I picked up and noticed knuckle was leaking at the pivot point. On both sides.
Looking at the diagram for the Bevel gear it looks like there is 1 o-ring (#4) a larger seal (#1 Seal oil), and an inner seal (#3 collar seal).

Is it suggested to swap all three of those items out while in there?

See image attached for reference
