Hey, I've been doing some searching and seen some videos but idk if I've come across one that is like this. I have an 03 evo 8 and when I turn to the right I get a grinding and sometimes whining noise. Any thoughts or suggestions would be great! I took a video today just after changing out my transfer case oil. The noise is worse when it is cold.

 

I leveled the fluids after it cooled and took it back out to no more grind or whine... I'm a bit puzzled as this is the second time this week I have changed the tcase oil this week. Here's a video of it just now. I will take another video in the morning as it gets worse when it's cold.

 

And the noise is back again in the morning... I don't get why it wouldn't make the noise at all last night but it's back after warming up the car for 15 min this morning in 45 degree weather.

 

What fluid did you use?

 

Been using the oem mitsubishi fluid.

 

sure its the t case or is it the rear diff?

 

It sounds like it's coming from the front. Can't say my rear diff is making any noise? No idea tho.

 

Any time I've heard of that it's the rear diff making it while you turn and it's because the fluid I think you have to use diaqueen or something like that. I saw that issue recently on the forums but it's because he swapped to the wrong fluid.
