Okay, I want to weigh the advice that I trust in, here on this site. I Just removed the 742-323 posi unit out of my donor differential. All looks good Except.... down inside where the spider gears live are little crusty nodules of rust on the faces of some the gears. What I can touch with a screwdriver seems to scrape off and does not appear to be eating into the surface. I cannot see the surfaces of all of the contents , it seems to be scattered around. Should I soak this in some way , with whatever, or rinse it with Brakekleen,... or have it taken apart for rebuilding? Lastly....should I just forget about it and Roll the Dice?? Appreciate advice! Thanks.

I have cleaned up a few like this and used them. You can use a piece of scotch bright pad were you can get in, rinse it with any number of products that evaporate. Use a magnet to pick up any bits, you can change the gear lube after 300 miles. If you have a fill or drain plug that is magnetic even better. From what you describe it doesn't sound so bad.
 
Run it. Make sure your vent bolt cap is clear and free.
 
if this is a clutch type SG, they are fairly easy to overhaul.

the clutch type are notorious for the cross in the middle to break. ive welded up a few.

may be a good time to ck it out, and throw some clutches in.
 
There's your problem, you have a "Posi" unit in your "Sure Grip" housing! :poke:
