Guys,
How you can recognize if differential is LSD or not?
2006 Cross Sports 2.0T JDM.

 

Type serial number into Google.

 

Lookup the part number

 

@Don Clark @hedgecutter Guys, car is on the way from Japan. I dont have a long 14\17 digit VIN number. There is a kind of number on the auction list. SG5-093929 is it the number?

 

If you look at my post again, you will see the image has Japanese writing on it - JDM Parts Database.
S11 - SG Forester
E - 2006
CRS - Cross sport 2.0T

27020 - Rear Diff assembly - LSD - part number 27020AA050

Just to make it clear

As an aside the UK seems to be a favorite place for Cross Sports to end up.

@Don Clark THANK YOU VERY MUCH!

I checked part numbers and its Viscous LSD. As far as I understand, two viscous small clutches are enclosed and have their own fluid inside, so any differential oil 75w90 can be used withOUT LS litera. Am I right?
if it was open type LSD, LS oil would have to be used.

 

Yes, no additive is required. Any 75W90 oil that conforms to GL5 standard.

 

@Don Clark Thank you! You are so knowledgeable.
