Weird oil came out of my rear diff almost aluminum colored, never seen anything like it before. I was going to put some good synthec in but instead will use 85/140 mystic red, to see what happens in the next few weeks.

No odd noises or other behaviour, any ideas ?

 

Well the bad news is the silver is metallic but not as much as I thought very very fine material.

 

how long since last changed? I had silver mud in mine (front n rear) from PO. Changed out 2 yrs ago and no issues so far.....

 

@XRAD Sounds about the same time frame, I suspect the the shop that was supposed to do both skipped the rear. That was 3 years ago, I will run the current stuff for a few months then drain and check.

The stuff in there was at least 3 years old

 

yep...or maybe water got in there.....Those diffs are pretty tough....pretty sure it will be OK unless no oil at all....

 

It was full, no harm in running the Mystic Red for a bit, took her for a short drive no new noises that is always good. Water is very possible.
