Just did the gear oil change on Toyo with 240K miles with Redline 75W110 and noticed seepage where the shaft enters the differential and also over the x-case fins. More appears on the case vs differential, although not concerned since the seals are so old but in any event wanted to get y’all opinion if this is normal given the age of the seals. Never towed all these years although dragged tree branches for clearing a few times
