Wheel Bearing Packer

That's how I've always done it and always will. I tried one off the crap on truck like 30 years ago. I don't like the bearing packers because they are a haven for dust and dirt. I never remembered to cover it up and dust and dirt accumulate like metal shavings on a magnet. So, I went back to packing them by hand. It's always clean and gets the job done.

That's the problem I have with them.
Bigger mess than they are worth, and you can't trust that there isn't any contaminants in the grease unless you seal them up in something or clean them first every time.
Not worth it to me.
