Rear diff identification.

I now have a 4.44:1 rear diff. I took the cover off and was trying to identify what kind I have. I have done some searching and I have had minimum luck finding out what it is. I posted this up on another forum and they said it might be a suretrac. If someone can point me in the right direction it would be greatly appreciated. thanks in advance.

 

yeah, that's a mechanical diff and more than likely a suretrac (came stock in a lot of subarus, just not in USDM WRXs)

an easy way to check is to spin one of the hub carriers. if the other spins the same direction, it's a mechanical diff

 

Pictures would help too.

 

there's a big giant picture in the OP.

 

WJM, input when you can.

 

oh ok I see how it is.

 

Fucking A. It is blocked via Fortiguard and I cant get to it on my phone.

AND there is no power at the house since yesterday afternoon...

 

LOL. No its not like that, I just want input from multiple people.

 

Does not look stock to me. If you can see all sorts of different gears inside, its a helical or torsen. If you see gears and fancy wedges, its a suretrac type. If you see clutch packs/discs, its a mechanical clutch type.

It is absolutely *NOT* a Viscous LSD.


A keeper for sure tho as long as its not noisy or binding like its a spool.

 

There appears to be some type of a vin by the main gear... Maybe you can look it up and find out

 

I checked the number that is on the diff it self. No dice. I checked multiple places. It really doesn't matter, I am just happy that the diff is not a viscous.

 

did you call nissan japan? don't they make all (most) of japanese vehicles' differentials?

 

You got their number?

 

Don't know if this helps but it does include tranny codes:
