Greasing bearings question
I am looking in the owner's manual for my axles (AL-KO) and a couple of things I'm unsure of. I planned on jacking up trailer to work on each wheel, but manual says it's not required (Ultrulube-equipp...

The difference is that when you hand pack the bearings individually you don't have to fill the void around the axle between the inner and outer bearings like is required using the grease gun method using the zerk. You have to fill that void before the grease will be expelled out from around the outer bearing and all that grease in the void is doing nothing to provide any lubrication to either bearing.
A tube might be a little too much, but around 2/3's of a tube would not surprise me at all and why I no longer recommend using the grease gun/zerk method when that is an option. Hand packing IMO is much better.

Seems to me that the diameter of the bearing and the diameter of a regular grease tube are about the same. The distance between the inner and outer bearing is a couple or 3 inches. The length of a grease cartridge is 10 or 12". It would seem to me that one tube would be able to completely fill the void of 3 or 4 bearings... especially because the bearings aren't hollow.
Then again, I hand pack my bearings because I am afraid of putting too much grease and greasing my brake shoes.
