buoymaker I'm just saying that if the oil level is right up there level with the seal more likely to leak. Same way with the differentials,that oil level is just below the seals but when you drive the oil level will give the seals a "drink"when you get not level,once back on the level it equalizes. The hubs have a pocket that holds oil for bearing lube,it gets changed as you drive and get out of level at times. It's not that the dipstick is wrong,but pans get changed,dipsticks get changed,dipstick tubes get changed. Item 2 and 3 happened to my one ton,when I drained it I got way too much oil,well PO put in a dipstick tube to tall raised oil level above rear main seal !! Would leak sitting in the shed.
