Grease zerk on axel.
I have a 1990's vintage Palomino and have always hand packed the bearings. Last fall I burned out a bearing. I noticed that there is a grease fitting on the axel that seems to exit near the back o...

I pack by hand and leave the center of the hub mostly empty as the grease does not migrate in and out of the bearing. The zerk will take a whole lot of grease as it fills the entire hub up with grease.
I almost started using the zerk until I though about it for a while and I realized that the zerk is probably good for an initial pack. But come next year at repack time I need to force an entire hub full of old grease through the outer bearing until I see all new grease.
The problem I see with this is the new grease only comes out of the base of the spindle at the 3 and 9 o'clock position. How can those two positions possibly force all the old grease out of the hub? It seems more likely that I'll have two little ribbons of clean grease pushing through the hub at 3 and 9 o'clock and a whole bunch of old grease left behind in the hub to mingle with the new grease once the wheels start turning.
I always disassemble and pack by hand so I know the grease is clean and new.
