Bluish-grey rear axle oil? Yikes.

[jtl909]

I just replaced the oil in my rear diff (Chrysler 8.25 on a 95 Sport) and it was dark grey with almost a bluish tint to it. Am I being paranoid or is this metalic particulate matter as a result of sheer? Smelled nasty, too.

That's the way mine came out.

You are not kidding about the smell either....

Haven't you read all the threads about gear oil smelling like flowers?

Probably not, because it smells like crap

It makes me vomit. No joke I threw up at the junkyard

I looked! I looked! I'm a relative newb and I do search but sometimes you gotta get the search criteria just right in order to hit on the right article.

As far as the smell, good Lord. I've had a couple Budweisers and I can still taste it in my sinuses. I'm not kidding, either!

Thanks for letting me know I'm not the only one. Makes me feel a lot better.

Whenever I'm draining anything, including engine oil, I always throw a big ol' magnet in there and fish it out later to see if I have any metal coming out of the (particular) fluid. When I changed my diff fluid it smelled funky and was a dark bluish-gray, but no metal. My TC fluid had a little bit of metal shavings, but no chunks. I always change everything waaaay before it's due since I'm driving an 18 yr. old rig. Gotta keep things going.

Gear oil is not engine oil or AT fluid, smells different.

I've taken to throwing one onto the oil pans of the cars we operate but having one in the refuse pan is a great idea.
