I use the "Hand in plastic bag trick". Put your hand in a plastic bag large enough for bearing cup and cone to fit in and seal. Trick is to turn bag inside out, scoop up some grease in your palm, take cone and starting with the wide side between the race and cage, push the grease in till it comes out the other end. Then move slowly all the way around till packed with grease. It dose not have to be 100% full. Just close. Now scrape off any excess and place the cup on the cone. Now turn bag inside out so you can seal. Takes a couple of minutes to do each. Do all at same time. Keep lid on your grease to keep dirt out. The number one cause of bearing failures is contamination of the lubricant. Bearing packers are nice new. Grease guns are nice new. After some time they both put dirt in to what you are greasing. Same thing with the big greas bucket. I would never grease anything except a 5th wheel plate with that stuff. No the largest tub of grease I use is 5 lbs. always closed. New grease gun tube, never refill. Always wipe the grease fitting and coupler with a rag before attaching and after. That big blob of grease next to the fitting is hiding the fact that the ball did not seat so after a while that u-joint will fail. Have fun!
