Well after 2 years, 3 seals, a replaced bushing, and paying for expert advise. I have discovered there was a Toyota service bulletin issued in 2012 for a leak problem around the plug that is pressed into the yoke. Toyota's fix replace the drive shaft. The inexpensive fix, remove the yoke, run a small welding bead around the plug, replace the u joint, reinstall the drive shaft. Changing the yoke caused vibration in some. I guess if you change the yoke you need to have the drive shaft rebalanced. Hope this save someone the trouble I have had.
