One-wheel peeling. Rear bar too stiff or fried diff?

I boiled 90 weight twice on the stock vlsd and also toasted it. Then I put 140 weight in the stock vlsd and didn’t boil it again but it was still toast. Seb just installed a wavetrac and we used 140 weight again. As for the diff, it’s insane. You can wot out of corner exit and slide super minimally. Only difference is you have to keep it loaded especially in high speed transitions but other than that I would 10/10 recommend

Its not that it just over heats, that VLSD fluid also wears out and there is no way to replace it. After 50k miles it will work less and less. This fluid is different from the gear oils people are mostly talking about here. VLSD fluid is not serviceable.

The silicone fluid is held inside the ring gear carrier. It's not replaceable. It's separate from the gear lube.
