pack the back side of the seal with bearing greese to help hold the spring on the seal in place when driving it in

drive it in to the shoulder stop for the seal

wash and repack the wheel bearing,it does not get lubed by the gear oil in the diff

the inner seal is right behind the wheel bearing and lock collor on the axle

the outer seal is the thin embossed metal shim seal behind the backing plate

the foam seal goes behind the bearing retainer and is to keep dirt out of the wheel bearing

there are no seals inside by the chunk,but it has a gasket for the housing

be sure to set the axle end play adjustment when it goes back together...the adjuster is on the pass side unless some one has moved it to driver side

if you replace the stock tapper bearing,it has to be pressed/cut off and pressed on,be sure to not mess up the adjuster,they do not make those any more might as well crack the chunk loose and change the gear oil while its has axle out

make sure to replace/clean gear oil off the brake shoes and drum with brake clean( I would replace the shoes if they are oil soaked myself)

I run the non-adjustable green bearings with the o-ring on them and did not use the inner axle seals this time,no leaks so far

greens can run with or with out the inner seals

good luck
