Pulled the center diff out of my trans last night. I took some pictures with my phone since I couldn't find a thread with any pictures for pulling the auto center diff. It's REALLY easy
Remove the six bolts holding the center diff cover on. Also scrape off the sealant on the upper right part of the cover (yellow mark):
Be very patient getting the cover/bearing race off of the trans, it fits very precisely into the case. You will need to slowly work each side and the top & bottom. Once you have it out enough you should be able to grab it and start twisting it in it's bore to slide it out.
Here's the cover removed. Get an oil pan under the trans because it's going to leak some fluid:
Next you need to remove the outer gear and tapered roller bearing. You can grab the roller bearing and work it out by hand, take note of the gear above (circled in red) when you're getting this out. You'll likely need to twist the outer bearing and work it through the teeth.
Now you'll see the center diff housing in there. To pull it out I used some channel locks with a rag to protect the splines and kind of popped it out. There is a retainer clip inside the center diff gear that holds the output shaft in. The clip is much like the one that holds in the passenger front axle so you just need to give it enough force to overcome it.
Here's the groove in the output shaft where that retainer clip fits. Often times the clip is long gone and the center diff will come right out, again remember to rotate the center diff so you clear the gear protruding from above:
That's it, all done, now take it and have it welded! 8)
