The red circle shows where the grease comes out. Between the inner bearing and the seal. The arrow indicates where the grease goes in. You can see that when the grease is pumped in it comes out one hole on the inboard end of the spindle
I am not sure how it infers that the grease comes out before the brg when I show in the picture (see red circle) and state that it comes out between the bearing and the seal.
Grease is injected at the zerk at the end of the spindle. It then has to travel through the spindle and then pass through the inner brg push the old grease down the spindle and through the outer brg so that new/fresh grease can get to the outer brg. or it can squeeze past the seal right beside where it comes out of the spindle. Like water it will take the path of least resistance. Also of note... the instructions state that when lubing the axle the EZ lube way you must be rotating the wheel. I am willing to bet that most people are not rotating the wheel when pumping in the grease.
As Ive stated before - if you're performing regular maintenance, inspecting your brakes and bearings at proper intervals then EZ Lube is moot anyway. There is no substitute for proper regular maintenance. Thats my professional opinion and I am sticking to it.
