Questions & Answers
Questions: My front seal must of had a small dust cover, not a large shield one like the rear. Mine looks more like the one in your video, however, I couldn’t get the smaller dust cover out of the old seal without destroying it. Is it of that much importance on the front Dana 25 differential?
Question By: Don on Aug 24 2019 12:59 AM
Please take an image of what you are referring to and email it to firstname.lastname@example.org. Typically there was just a hub oil seal there and an inner oil seal is all in the front.

Questions: Is the dust cover required or can I remove the old one and just slide on the new seal?

If you have the style that has the shield I would put it back on.

Questions: Is there supposed to be a "cover" on one side of the seal? The seals you sent me look the same on either side as per your first picture. They do not look like the one in the video.

Your yoke has a dust shield. The spring side to the seal goes towards the differential.

Questions: I have a '47 CJ2A with a Dana 41 Axle (Semi-Floating) and noticed in the Parts List manual it does not mention that I need this Pinion Shaft Oil Seal. Yet on this webpage it says it is for the Dana 41. I can not find this Pinion Shaft Oil Seal anywhere in the diagram. It just shows that I will need just a gasket, part No. 636565. Please help, thank you.
