Uh-oh! Looks like I'm in trouble!
Without a seal and hub to examine, it looks like Dave positions the seal
off of the bearing's race. It may be that the end results are similar, but
we approach the problem from different directions. The only one of his
dimensions I match is the 2.900". I believe that's the OD of the rubber
part of the seal, with the metal housing extending outward from there -- to
just beyond Dave's 3.080" diameter.
My tool positions the seal in relation to the knuckle; it's cut arbitrarily
deeply at the 2.900" diameter to clear the rubber (and anything else inside
the seal). A 3.100"-2.900" diameter ridge immediately outside there
catches the metal of the seal Another ridge 0.040" higher than that one
contacts the knuckle's machined surface to set the "proudness" of the
seal's metal.
Unless I'm mistaken, Dave's tool is intended to position the seal correctly
in relation to the bearing, regardless of anything else. Mine depends on
the sanctity of the design and construction of the components and merely
sets the seal at 0.040" proud of the hub.
Guess I'll have to find a seal to check out -- even though I now run the
1-Ton front suspension. :-(
