i baught a version 5 impreza that i broke not so long ago, i was advised that it had a cusco rear diff, i have removed it now,

im wondering how to identify it as cusco diff, how can i tell itsa a cusco diff & not a standard 1??

 

heres a pic of when it was on the car

 

Same as any other, Its the insides that will differ.

 

Or more specifically the diff. assembly will be non standard (Cusco), whilst the crownwheel and pinnion will likely be standard...

Open it up and have a look

dunx

P.S. Many years ago a dealer sold my pal an Escort with Pentax shock absorbers....

 

here are some pictures now i have the diff out of its casing

is it a cusco as i havent seen a standard diff to compare

 

take a look at my thread, theres some pics of what im told is a cusco rs diff......

 

that is a standard non plated LSD diff.
