Default RE: Replacing the front differential seal HELP

ok so i used an automotive stethoscope and pinpointed it to the drivers side area

so i took out the axle and the bearing was exploded and everywehre

i also noticed that it was like completely dry in the area by the bearing all the way to the diff
is there supposed to be fluid going twards that bearing?

if there is, what do i need to do to fix it?

so far the parts list is the wheel bearing and seal (im going to do both sides while im at it)

what else will i need to get?

Gear lube and posi additive...RTV
Should be gear lube in the tube to the bearing,not alot just a small amount...How can you fix this?Keep the diff full...Bottom of the fill plug..how the axle itself look?Alot of the times if the bearings shot the axle has damage...bearings not gonna fix the whole prob..the axle should be nice and shiny(so to speak) where the axle bearing rides.If its pitted or looks rough,you'll need a new axle.Sometimes you can find what they call AXLE SAVER BEARINGS....relocates the bearing on the axle comes with a seal...Also solid Pinion Spacer..I torque the pinion nut to 70 FT lb's ,yes ft lbs with a SOILD pinion spacer with locktite on the pinion nut.

yea, i looked in the tube and there was no fluid

i recently just replaced the rear seal and filled the case
i dont see how no fluid could have gotten to the bearing
its kind of strange.

i put 2 quarts of fluid in there and some friction modifier

is there any acceptable pitting?

because when i run my fingers over it there is a tiny bit of unevenness but like its shiny and somewhat hard to notice the pitting

what could cause the rear to not allow fluid into the axle tubes?

I'm glad you got it back together. I was going to post some pics of axles I have laying around. One showing acceptable wear and one with unacceptable wear to give you an idea of what to look for. But you already haveit back together. You'll know if you should've replaced the axles if your noise comes back soon... new bearings don't last long on bad axles. There is nothing that can keep lube from going in the tubes and getting to the bearings except not having enough in the case. Make sure you fill the case up to the proper level and you'll be fine. Good luck with the steering rack... they can be fun.
