It is just the way it looks. Take the nuts
off, rap on end of axle to loosen taper
locks. I have a vise grips that I ground
one jaw to a v for spreading the taper
locks. Pull the axle out.

It's a GMC truck about 2 ton model. Like Belgian siad then knock the seal out from the front. Catch the bearing as it falls out. IF you remove the wheels down to the hub abd drum. You can set it over a clean 5 gallon pail and catch the pieces in there. If you jack the side being worked on up about 3 - 4 inches you will not lose much oil just what is in the hub. When done and oil refilled jack the other side up or run it on a 3-4 inch block and let set for a couple hours then level axle and recheck oil level again. The tilt lets oil get back to the bearings and hub. And need to be level to check oil full till it will run out check/fill plug hole. About 3 gallon if you drain it.

When finishing up, set up the wheel bearings to 0.001'' to 0.003'' of ENDPLAY, do NOT ''pre-load'' them.

Trial fit the seal on the axle housing before installing. Put seals in a 73 or newer truck and found out doing the second one that the first was leaking. A collar/spacer needed to be installed to the axle
housing to match the seal.
