today i just changed my read diff oil and ive NEVER had a problem with any noise untill just now.. as i was making a left onto my street (car was in neutral) as i slowed down/started to turn the car was making this nasty grinding noise and it did it as i was slowing down into my driveway as well.. i used 80W90 for my oil.. is that was it causing this?

 

I has similiar issues but from the front only during a sharp turn. Mitsu said it was normal, I called BS and changed out the differential fluid and WHAM no more problems. If i was you, I would change out with OEM mitsu fluid. What fluid did you use?

 

Hope you used OEM Diaqueen LSD Oil...

 

super tech SAE 80W-90 gear lubricant

 

yea im going to the dealer tomorrow and gettin some to swap this **** out

 

so use this in my rear diff and X-case

 

^
that is correct

 

You put Wal Mart gear oil in your Evo?

 

Maybe Im wrong but isnt there an additive in the Diaqueen that the other stuff wouldnt have?

 

Rear diff even has a warning sticker on it "LSD OIL ONLY"
NOT GOOD

 

Nothing but IMO. Anything else and your asking for trouble

 

NO **** same thing went through my head.

EVO owners kill me sometimes.

 

picked up some diaqueen already going to change it now, also checked the rear diff to see if there was any damage/blown. everything is good to go with no damage

 

Consider yourself lucky...always use OEM fluids...no reason not to
