I'm going to sound like a DOLT here, but I'm having a hard time
understanding how this works ??
Won't the grease just slide through the splines? How does it get
forced up into the bearings ??
Is there a cut-a-way drawing of the hub and this tool in place ??
Ray,
I do now have a cut-a-way drawing of the hub with the bearing
lubricating tool installed. You can do a search for Dave Lenzi's
knuckle seal installation tool where he has a cross section of the
front hub. Just visualize moving the axle inboard about 3/8". The
front wheel bearing lubrication tool is a two-piece collar that you
bolt together around the axle in between the inboard side of the
knuckle and the outboard face of the CV joint. When the axle nut is
slightly tightened, the seal mates with and slightly compresses the
knuckle radial face seal on the outside face of the collar and
against the face of the CV joint on the inside surface. The axle has
a large radius where it transforms into the radial face of the CV
joint and it forms a metal-to-metal seal around the axle on the
inboard side of the lubrication collar.
When the grease is added, it fills the cavity inboard of the knuckle
seal and the axle adjacent to the bearings. It takes very little
pressure to force the grease into and fill the bearings with grease.
When the bearings are full of grease you can feel the grease being
forced out the vent port on the lubrication collar. If you plug the
vent port and keep adding grease, it will be forced outboard between
the bearing inner races and the axle and on out the axle splines.
If you cannot find Dave Lenzi's cross section drawing, sent be an off-
net e-mail and I will e-mail you a copy.

you mean these
http://www.gmcmhphotos.com/photos/showphoto.php?photo=25492
looks like this procedure forces the old grease ( and filings) through the
inner bearing and into and out through the outer bearing -- out through the
outer seal
where as the the Zerk technique forces the grease between the bearings and
the old grease (and junk) out of the bearings ?
Is this the case?
