[Tom Skinner]

Gents,

As per usual Andy Bernbaum stuff is Great. Question below my Inner Axle Seal (New) Which way does it Face (Out - In)

Sorry to start a new thread I didn't want my old one ignored.

The spring in a seal goes toward the oil/grease.

Sam,

Thank You!

Andy wasn't there when I called, he would have told me that.

I will call them tomorrow and tell his helper, also I will order new Wheel Cylinders for the front Brakes.

Thanks again!

Technically there is gear oil on one side and grease on the other.

Both seals, inner and outer, should be installed with the sealing lip in. You want to seal the axle oil in the axle, and out of the wheel bearing with the inner seal. And you want to keep the wheel bearing grease in the bearing, and out of the brakes with the outer seal.

Standard application is install the seal spring toward the oil. In this case the inner seal spring should go toward the more fluid lubricant, the gear oil.

Actually standard application is to install the lip seal so that it points into the source of pressure that way it is pressed more firmly into the shaft to seal it in the Advent that there is a pressure buildup. So you want both lip seals pointing to the center of the axle housing on either side it doesn't matter and make sure the axle vent is clear

Looks like we are all in agreement......for once.  😄
