Noisy vlsd....Need help

[zenki s14]

I bought a s13 vlsd a year ago. And now its noisy as hell. At slow speeds, and in tight turns. I already changed the oil, can't figure it out. Im guessing that the vlsd is dead? is there anything else I should check before putting back my open diff?

VLSDs only work so long, and a s13 one is about 10 years old, it wouldn't be surprising if it's going out, from what I here from peepz in japan, they don't last all that long if u thrash on them a bit. Sounds like the perfect excuse to upgrade :)

If you're hearing grinding noises, u should think replacement asap.
