I have a 1995 wrx. The diff casing has a little gold lable on it with TR printed on it. Does TR mean 4.111. My Subaru book states the 1994/ 1995 wrx with solid read disc will be fitted with a 4.111. I think my diff has gone and don't want to get the wrong ratio replacement. Can anyone help !

 

Gearbox code sticker is just near the starter motor, and its also on the chassis plate on the front suspension top mount area.

Thats the only way really.

 

Thanks for the pointer
