Rear Diff Chunks!! (1 Viewer)

[lesgarten]

I decided to drain and change my rear diff oil.

I had the usual slime on the magnet. But also had some small sharp chunks maybe 2-3mm square.

What would Corn pop do here?

Pics please

Pics please

Thanx for the quick reply.

I spread it out on a paper towel. Now that it is away from the magnet, it feels like several thin shavings. Very brittle.

The "bunch" around 4:00 in the first picture was a single piece that was flat and crumbled to those small bits when I tried to move it around.

Think of it as chewing ice. Eventually, you'll chip a bit of a tooth during your lifetime.

It's fine

Well, it's fine until it isn't. Those chunks of metal are chunks of gear teeth likely. So something is up. It may be ok for awhile, so I would run it, but watch for increasing gear noise and check for metal again in a few thousand miles.

Pretty unlikely. Everyone wonders this the first time they remove the magnet. Could be scale from the housing, flakes from the spider gears or side gears, etc. I doubt chunks are missing.

It was mainly Flakes, very thing shavings. I thought it was chunks until you asked me for pix. I then went and dug it out of the trash can and spread it out.

It felt like a chunk or so at first because the magnet was holding the pieces together and it was hard. I normally expect only metal slime to be on those magnets. Something that felt like a chunk had me mortified

That's pretty normal. don't worry. That's why the magnet is in the drain plug.

As @nukegoat said, you're fine.

I found a couple small shavings like yours on my center diff magnet at around 146K. At around 172K now ... no issues.

Thought I would round this thread out with a few better pix. Two different pieces of Junk pictured.

Filled up the diff today and we'll watch it, or at least that's the plan.

Following up on this ... changed my diff and t case fluids again today after 30k miles. No issues and no chunks/shavings in the past 30k miles.

Better rip it out and get a locker.
