What shape was the seal surface of your yoke? I like to polish on them with some scotchbrite and lightly lube before install as sometimes a light burr can be present. Also, these seals are rather fragile and can be damaged if not installed just right. Add to that you can get dud seals. Before install, you need to get all the old sealant (stuff that looks like paint) out of there. The seal must be put in as gently and straight as possible. Look at the back of the seal to ensure the spring is securely in place, not loose or missing. I find them more often than I wish I did. Lastly, make sure your pinion bearing preload is right and the pinion bearings themselves are good. If the bearings are loose it will damage the seal and leak again. On the upside, its a cheap seal and easy to put in.
