TRD Runx with an LSD??

Hi, I'm brandnew to this forum and thought I'd post a question I have regarding the title. I was planning on changing over the diff fluid as I'm not sure when it was last done. While I was getting ready to do it I realised that the two front wheels spin the same way when turned. Now I've come to two conclusions after looking it up. Either it's a screwed up normal diff or possibly an lsd? I'm not sure. Did the TRD runx even come out with a lsd? And also what grade diff oil do you reckon is optimum. Thanks.
