Get a coarse wire brush and scrub it good.

I used aircraft paint stripper on mine. Start with it dry, goop it up heavily, let it work for 30 or so minutes and pressure wash. The stripper does well on grease not to mention any remaining paint. I had "California desert baked" grease on mine and it came clean after two rounds of the above treatment.
With the help of a breezy warm summer day, I cleaned, sanded, primed and painted it in one day. Paint has held up well.
Where can I get some? Maybe I'll go pick it up on Friday.

But I'm still having trouble getting the clumps of 40 year old grease and dirt off.
As you know it needs to be surgically clean for the paint to stick/last. You're getting close, dont get impatient this close to finishing
Yeah, that's why I need to finish this by Friday. Diff housing and parts is going out on Saturday.

If you've spent more than an hour or two cleaning this your either doing something wrong or don't have the right equipment.
I cleaned mine on the back of my tailgate with engine -brite cleaner a hose, Wire brush and compressed air blower. Take a screwdriver and pick at or scratch off the heavy gunk. Be sure to pick out the clumps in the spring perches other than that because the shape doesn't have any concave surfaces there really shouldn't be anything that the wire brush can't handle.
I had a coating off Road grime about an eighth inch thick in places on the tubes that came off easy with the method described above. Also it's easier to scale/screech/wire brush it Before applying the decreaser.. this way you remove the gack rather than break It down and smear it all over

Autozone usually stocks some or any heavy duty paint stripper from the home improvement store will do it.

I have a couple questions before I reassemble my rear end. I got the housing painted and my carrier is completely built. I just have to do the final assembly. I got all of my parts from Dr Diff. Everything was replaced with Timken bearings and I should have all of the proper gaskets on hand. After the carrier is set on with the gasket, what's the best way to install the axles and setting the proper axle play? I've read my service manual and it talks about utilizing the backing plates and a dial indicator to set it, but I don't plan on going to drum brakes and I don't have a dial indicator on me. I've got tapered axles on my setup. Also, there seems to be a spacer that's supposed to go in between the axles in the carrier. How am I supposed to set it in there without dropping it in the housing before I install my axles? Thanks for all of your help guys! You've been great help so far.

Coat that spacer with thick grease and shove it in.
So just coat it in grease and throw it in the carrier before I install it in the housing? Then grease up the axles and slide the axles in adjusting the axle play?

Install the carrier and the axles and set the bearing end play. Make sure you pack the axle bearings as these are not lubed by the gear oil. Once you get it all buttoned up, pull the fill plug and fill it up. Should take about 2 1/4 quarts. 80W/90 will work fine. Add Limited slip additive if its a sure grip. Done!!

My friend already packed the axle bearings but I'm going to add a little more. I also just bought a gallon of 80W/90 and the limited slip additive. It's a true trac diff. Not the clutch type.
As for the axle end play. Since I'm not using the drum brake backing plates and I don't have dial indicators, do I just try to get the axle as close to zero end play as possible?
