I just did mine not long ago... I jacked up one at a time, pumped the grease while turning the tires... I was surprised that it took about a tube per wheel
That would surprise me too, usually it takes about a golf ball size gob for each bearing.
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.
