I wonder if "knuckle pudding " would work? Over at the Willy groups the guys mix 90 weight oil with grease half and half to put in the universal balls on the front 4wd axles. Say it stays in better, doesn't leak past the seals on the ball.
Yep, that should work fine. That is what I did, but I used 120 weight gear oil and bearing grease. Mixed to self leveling consistency that I felt would still allow adequate lubrication to the top bearing.
