I pulled the axles and the backing plates, found the oily goo I expected to and plan on putting "sure seals" in after packing the bearings with grease. I think I can save the brakes with a good cleaning. What surprised me was I found no shims on either side, just two thin gaskets one on each side of the backing plate. The FO-4 and '39-'53 master parts catalog show only shims on the trumpet side of the backing plate. Am I missing something or did someone put this rear end together in an unconventional way to try and stop the leak? Thanks in advance.

I have seen what you are describing many times on the outer trumpet to bearing hub. Gaskets or shims will both seal in the oil. The shims are so thin that they conform to the metal irregularities just as gasket materials do. The only reason the shims are present is to add additional clearance to the preload on the axle bearings. The ends of the axles must butt together in the middle of the differential in order to have any preload on the bearings. The reason for preload on the bearings is to allow the bearings to carry the weight and thrust more evenly on the entire surface of the bearing races. If there is no preload the bearings only touch the race in one small place and this small spot is carrying the entire load and the part of the bearing that is not touching the races is not doing anything but riding along for the ride.

This thing about one wheel turning one way and the other wheel turning in the opposite direction and both wheels turning one way just does not make sense to me. Maybe some of you can show me the reasoning behind this. To my knowledge if their were not enough bearing preload on the axles and the transmission was out of gear (in neutral) and one wheel was turned the other wheel would stand still and the pinion would turn. If the transmission were in gear so that the pinion could not turn then one wheel would turn one way and the other the opposite way.
This would be true if their were too much preload or not enough preload.
I think that you would have to know if the transmissoin was in gear or not to know anything by this test. I also thing that if the bearings were preloaded so much that by turning on wheel that the other would turn the same way you would have far too much preload and this could cause premature failure of the axle bearings.????? ?????

Thanks, I feel better knowing it to be somewhat common. Since it worked fine the way it was other than the oil leaking, I will just put it back like it was plus the sure seals.

Maybe it does not need shims. You gotta do the "Lift the rear Wheels" and turn one axel and see what happens. Then check to see if the bearing preload is correct.
Happy Motoring

Thanks Claus. I forgot to mention I did all that, wheels turn opposite like they are supposed to so I guess I don't need shims. But what about the gaskets? Were they just left out of the drawings and my parts list. I saw them mentioned for the 8N's but not the 9 and 2? Do I not need the gaskets? Thanks again.

The gasket you mention is also acting as a shim for your preload. If you put it together with no gasket and the preload is acceptable, you might try locktite's 518 gasket maker,or if the thickness of the gasket is better, then use that or an equivalent thickness shim, with or without some sealer. Sounds like your real close.
