I opened up the read end on my 95 astro with 90K miles. Just wanted to see if things look ok or need repair from those in the know. I have metal shavings around the magnet. Here some pics. I have trying to track down a noise when backup up with engine cold. Sounds a little like heat shield rattle but a deeper sound. Anyways here are the pics.

So, it that considered a lot of metal shavings on the magnet?

Anything else I would check while I am in there?

The magnet is there specifically for that, looks normal from over here.

Looks normal to me. It’s dust from wear but no chunks.

Use a can of brake cleaner and get out whatever is still sticking to everything. It works really well.

Then put it back together.

metal on metal is inherently going to wear even with oils lubricating them. at 90k with that much metal its probably the first time that rear diff has been serviced. totally normal amount of wear for the miles

They ALL have metallic fuzz on the magnets when you pull the cover.. it's just a matter of how much is too much. Unless you're having a specific issue, it's probably not a problem. Fresh fluid and your back on the move.

PS: I ALWAYS put the new gasket on dry... never a leak! Just be sure cover is clean and flat! Tighten bolts evenly and smoothly.
