Yoke Plug/Cap Leak

Driveshaft Yoke Plug/Cap Leak Fix
Just had a slight drip develop from the driveshaft rear, not the seal at the diff but seems to be from the yoke plug/cap. Have to check the diff fluid as its likey a bit low but I've found 3 options for a fix online :
1) clean the outside of plug while still installed and jb weld the outer area around plug.
2) Remove yoke, and then the plug, then clean and RTV inner area of plug that goes into yoke and install back into yoke, then RTV or JB Weld outer
3 ) Replace the whole yoke (heard there may be an updated one?)
Anyone else have the issue and can comment on the fix they used and how long it lasted?

So after cleaning the area where the leak is, it looks like the yoke plug/cap is on the front of the diff and the rear has the pinion nut which is where mine is actually leaking. Leaks thru the threads and more in the warmer weather it seems. Will likely try the Blue Devil stop leak that is ok for differentials and see if that stops it.

Checked the vent hose and is seems ok - put a flexible wire in the tube and it went in all the way to the junction block it sits on with a couple of brake lines, no gunk on it.
