I'm working on a Dana 60 that came out of a early (1966 to 69) B body, I noticed that it does not have a oil passage under the rear pinion bearing like all the other Dana 60 I've worked on. This is probally the only OEM early B body Dana 60 that I've work on in a long time Is this normal or not I have one other Dana 60 in the shop now but no OEM Mopar B bodies or other OEM Mopar Dana 60 now, the other truck Dana I have, 60-2, I looked at has a passage from the front pinion bearing back under the pinion gear to the back that comes out behind the rear pinion bearing This does not look like a casting flaw, it looks like it was designed that way

Cab, Pics might help. Tim

Cab , Dana 60's are 66-67 and then 69-70 for B bodies . I have a 68 and 70 at home I can look at .

The build number and date code are stamped on the right axle tube ...

I just did a 60 the other week, it had that oil slot, and I just yesterday did a 70, it also had that slot, I know it did because there is a nasty pocket back there that chunks of debris can hide, and a total pain to get it all cleaned out. Maybee the really earlie ones dont have that. The 60 I did was a 1970 unit out of a charger that was now in a 4x4 1/2 ton dodge.

The passage in the bottom of the pinion bore usaly goes from the forward side of the front pinion brg to the area between the front and rear pinion brgs (to allow excess oil from building up on the back side of the pinion seal) I don't recall ever seeing the lower passage on Dana 60 go from front to back...there is a pocket in close proximitythough.

This picture is the B body one I'm working on, the passage is blocked under the rear pinion bearing

This is a picture of the B body front lube passage that goes from the front of the front pinion bearing to behind it and stops between the front and rear pinion bearing

this picture is of a Dana 60-2 that has the oil passage from the front pinion bearing area existing behind the rear pinion beraing, it is not open in between the two bearings

Well that is a drain back right ? so it would fill that area and only way it would drain back would be though the bearing..I would think that the seal would leak.. I got one here I will go look at it..it also came out of a truck//

Buddy I found my housing it is in the trailer under the rear of the car(dart) laying on the foor and I can't get the rear door open because of where it is park. and I can't move the trailer because I got the wheels and tire off it !so hope someone else has one they can look at..might be a flew weeks before I can get to it !
