The EZ Lubes were really designed for boat trailers to give a pump or two to rid any water seepage but they have matriculated into rv's etc.
Hope it helps Happy Trails
I think you are confusing EZ Lube axles with Bearing Buddys.
Bearing BuddyAn EZ Lube has a zerk threaded into the axle. The grease is forced through a channel in the axle to the back of the hub where it comes back through the bearings and out through the front. A Bearing Buddy is a basically dust cap with a zerk in the center. It has a spring loaded mechanism on the inside to keep pressure on the grease which keeps water and air out. The grease has to be topped off occasionally.
One does not have to use the EZ Lube feature if they would rather do bearing maintenance by hand.
