Yukon one piece axle leaking

I have the Yukon axle on my 80' CJ7. When I came out to drive it the other day oil was coming out of the rear driver side behind the tire. It must of just happened because oil was still flowing out. So my guess is axle seal is leaking. My question is since I have installed the Yukon one piece do I need a special type of Yukon seal or can I just buy the one that fits my jeep. Also is this a hard fix or just worth taking to shop and having some do it for me. Not sure how much would run to have done. Thanks in advanced for help.

You can almost always get the numbers off the seal or just measure the outside diameter and the Inside diameter if it has a double lip or a single lip in most cases just purchase the same type. The Id and od Can be taken from points of contact!
You are the only one that can say if you are up to the task.
For me it is a cinch but I have the tooling and fifty years in turning a wrench.

Most 1 piece axle sets use stock AMC Jeep inner and outer seals. Some folks report having difficult removing the old seal because of the bearing spacer ring.
