Tranny leak at drive shaft

[79RaMNit]

So I'm getting a lot of vibration and transmission fluid coming out of the drive shaft where it meets the transmission. Just wonder if anybody could tell me how to go about changing the seal and what its called. Not a mechanic but I've redone most of the stuff on this truck I understand how it works I don't know if I need any special tools , any input would be helpful thank you

I don't know how I missed this one, but you've probably figured it out by now. It's a relatively easy fix and lots of good Utube vids showing it done. Hopefully, you've already figured that out,
