Gear Lube in CV to Differential Flnage

1slow370 · 02-23-2021, 07:11 PM

i have never seen a hole straight through the stub shaft.. usualy there is a little divot from the centerdrill used for machining but it shouldn't go all the way through? i would be tempted to say it is a defect but nissan might have changed it. it we be a really stupid place to put a vent holeas none of that area is sealed. i would be tempted to say someone lubed it for easy dissassembly. check to see if the hole goes all the through the stub flange if it does i would check with a dealer to see if they made a change to it and if not get a new stub flange.

The stub axles I have sitting on the bench have centering dimples for machining. But no hole all the way through.

Check the back side of the CV joint for anything that doesn't look normal.

This is what I thought. OP pop the stub axle out of the diff and see if it's damaged. If not I bet somebody just lubed the crap out of it when they put it together.

What point would have they lubed for disassembly, bolt flange to CV or stub axle to housing?

Upon further inspection there isn't light shining through the stub so I assume the hole doesn't go all the way through.

The only thing I can think of. This may have been a part before and they coated it with oil to keep from rusting.

there is only a fluid seal between the stub and the carrier housing if you had a leak you would expect fluid to be everywhere except where it is in your photos lol
