camper axle lube question ?

If you look at how the EZ-Lube system works you will see that a few pumps of grease initially won't do much. The grease flows through a channel and comes out between the rear of the rear bearing and the grease seal at the back of the hub. The first time you fill them they will take about a half tube of grease. The grease will flow through the rear bearing and come out the front of it. It will then fill the void in the hub between the front and rear bearings and then go through the front bearing and out through the vent hole on the front near the Zerk fitting to indicate it's full. You need to have the wheel off the ground and rotate it while greasing with a hand grease gun. A pnuematic gun will have too much pressure and will easily blow grease around the rear seal and onto the brakes. Once they have been greased in this manner you can then pump 3-4 shots into them but you still need to rotate the wheel while doing this. I prefer to grease mine the old fashioned way by taking the hubs off and repacking the bearings by hand..
