rear hub grease seals
How far into the hub do the rear hub grease seals go on my 1940 ford rear end drums?

Re: rear hub grease seals
The seals should be driven in far enough to clear the snap ring groove.

Re: rear hub grease seals
Well that is confusing, since the snap ring is against the bearing, and the seal goes in after.

Re: rear hub grease seals
Here's a few photos that may help. I tapped the seal in so it seats on the ridge in front of the bearing. Car is 40 Ford. Double check to make sure you have the seal facing the correct direction. I am not sure I got it right. The last photo shows a 40 ford rear hub i bought in 1964. Notice how it appears to have grooves for 2 snap rings - one for the bearing and another for the seal. Were some rear hubs made like that configuration or are my eyes playing tricks on me.?

Re: rear hub grease seals
You will be fine as that seal is pretty snug.

Re: rear hub grease seals
Seals have a "V"shaped sealing element. If you apply pressure to the "top of the V", the V will spread out and hold pressure. If you apply pressure to the "bottom of the V", the sides will collapse allowing pressure to pass. In a rear end, you want ALL seals installed to keep pressure away from the brakes. That's ALL seals, even at the bearing at the front of the torque tube.

Re: rear hub grease seals
I've installed more of these than I care to recall. Each and every one required that the bearing be installed and THEN the seal and finally the snap ring.

OK, Thanks, Mike. Guess I need new spectacles.

Re: rear hub grease seals
Mine have one snap ring, and it is right at the bearing, not at the seal. You may have done many of these, but not this one.
