I measured the current yoke as best as I could with my digital calipers. I'm getting 1.830"

This Sonnax yoke lists its journal diameter as 1.886"

I measured a spare bushing and it's 1.892" so it's very possible that the yoke I have now is undersized. The seal that I have has a listed inner diameter of 1.829" which is probably why it's leaking.

I was going to order that Sonnax yoke, but I found a Dana one for less money that will most likely still be an upgrade. Dana lists the diameter as 1.885"

I ordered a Dana yoke and a new Spicer 1310 joint. We'll see what happens.
