Hi bro/sis

Since some days i can hear like a roaring sound coming from my rear differential. Am running an st-205 engine with torsen rear diff. I drained the oil n found a weird colour. the sound is like a purr even when am on neutral i can hear it or when driving. am down plz help:(

you can hear it even when you're in neutral??? do you mean neutral standing still? or neutral and coasting?

cuz if its neutral and standing still then i'd say look somewhere else

but if its neutral and coasting then you've got problems

either chewed up teeth or a bad bearing back there.
