Well, I'll be hitting up the junk yard and keeping this one as a spare. I went to a trans shop and the guy said it was not normal. He said he could rebuild it for around 350$. I passed the offer. If I am able to keep this car long enough, I ill end up rebuilding the differential myself with an LSD swap from a Surpra MKIV NA small diff or possibly a TRD unit if I can figure out comparability!
In the mean time, I will install a junkyard unit.
