Axle Oil Seal

[yukgoon]

I have an 82 F100 with a inline 6 2x4 with the standard rear end. I am replacing the rear axle bearings due to leaks. I have found what looks like an oil seal inside the axle and cannot find out how to remove it or replace it. Has anyone ever done this and if so what is it called.

Removal, Units w/Ball Bearing


Remove wheel assembly.
Remove brake drum from flange.
Working through hole provided in axle shaft flange, remove nuts that secure wheel bearing retainer.
Pull axle shaft out of housing. If bearing is a tight fit in axle housing, use a slide hammer type puller.
Remove brake backing plate and secure to frame rail.
If the axle shaft bearing is to be replaced, loosen the inner retainer by nicking it deeply with a chisel in several places. The bearing will then slide off easily.
Press bearing from axle shaft.
Inspect machined surface of axle shaft and housing for rough spots that would affect sealing action of the oil seal. Carefully remove any burrs or rough spots.
Installation


Press new bearing on shaft until it seats firmly against shoulder on shaft.
Press inner bearing retainer on shaft until it seats firmly against bearing.
If oil seal is to be replaced, use a hook-type tool to pull it out of housing. Wipe a small amount of oil resistant sealer on outer edge of seal before it is installed.
Removal, Units W/Roller Bearing


Remove wheel assembly.
Remove brake drum from flange.
Working through hole provided in axle flange, remove nuts securing wheel bearing retainer.
Pull axle shaft carefully from housing to prevent damage to outer seal rubber. Use a slide hammer type puller to remove tapered bearing cup from housing. Remove brake backing plate and secure to frame rail.
If the axle shaft bearing or seal is to be replaced, split the inner bearing retainer.
Press bearing from axle shaft.
Inspect machined surface of axle shaft and housing for rough spots that would affect sealing action of the oil seal. Carefully remove any burrs or rough spots.
Install outer retainer plate on axle shaft. Press lubricated seal and bearing onto shaft until firmly seated. Oil seal for rear drum brake equipped vehicles is different than that used on vehicles with rear disc brakes. Seals used with drum brakes have a gray metal colored outer rim, while seals used with disc brakes have a black or orange color.
Press new bearing retainer onto shaft until seated.
Installation


On 1980---84 models, place a new gasket on each side of brake carrier plate, and slide axle shaft into housing. On models with roller bearing, ensure outer seal is fully seated on bearing.
Start splines into differential side gear and push shaft in until bearing bottoms in housing.
Torque bearing retainer nuts to 20---40 ft. lbs.
