Well I ran some thicker gauge wire to the coils, the old wires I think were too small and were causing it to break up. New wires in and the break-up seems to be gone, however there is some sort of strange buzzing sound coming from the rear under hard acceleration. No idea what it is yet. I looked under there and everything seems normal. I drained the diff and there is quite a bit of fine metal shavings. The magnetic drain plug was pretty coated in stuff too. Wondering if something is going bad inside there. Here's a pic kind of showing the metallic flaking. I know some small flakes aren't totally abnormal, but this seems like a lot to me. The pic doesn't really show that well but you can see some of it. Thoughts?
