46002024 GM 7.25 IFS 4WD & AWD Output Seal Right 01+
12471617, 46002024, SABO 7574
So the first number is the AAM part # as the secret OEM for the GM part # 12471617 that is actually the right hand side inner axle shaft or...
the Intermediate shaft seal (inboard) aka Axle Inner Shaft Seal aka differential INBOARD seal (the one next to the oil pan for the intermediate shaft). I'm gonna ask the local shop to do the job. The dealer said it's leaking - so we'll see. I can't talk to the mechanic at the dealer. And then the local mechanics keep insisting the dealer didn't do their previous repairs (and send me back to make the dealer redo the work). haha.
Here's what I wanted to tell you - turns out this part is listed as not available by GM OEM or direct parts supply. You can order it on Amazon but - the supply distributors get the AC Delco. So this person discovered the AC Delco part is too big - And so people keep having to get the too big leaking part replaced (under warranty). So the OEM was made by AAM - and NOT AC Delco!!
So it turns out this part "leaks" if it is 1.25 inches and that is the size of the AC Delco part.
So here is from a video of taking out the oil pan - but here he says,
"There's the Diff Out...you can now see a line of sight to all of the oil pan bolts"So that shot is from the FRONT of the car - now that I look at it - and the differential is going off to the right (which is the left side or driver's side - as the side is based on looking forward)...
Let me double check - he swings the camera around so it's confusing.
OK so here he just FLIPPED the camera around. So now we are looking with the left side forward.
I'm gonna now go to a different vid that actually shows the SEAL - Kevin nadeau.
OK if you compare this image with the top two - that's the seal that has to be replaced. He could have done it then as he says it is leaking! He says he got the new seal but I told him how the AC Delco seal still leaks. So you can see this is upside down and is the bottom "half" of the oil pan or an extension of it.
Let's put up the parts diagram.
OH wait - here we go! Kevin Nadeau has it:
So to the right is the oil pan and to the left is the front differential. So I was thinking at first - just spray that area with Permatex diff Seal fix (rubber in a can). But the seal has "tines" that lock into the bearing or whatever and so are under load pressure. And also you can't get to the back side of the seal.
So here you can see the differential is on the left side or driver's side - facing the front.
OK let's get an angle to lineup the diff better:
