I'm getting ready to rebuild my front diff with new OEM 4.3 ring and pinion. I'd planned to have them cryo treated to improve their strength but after reading around on the net I'm less sure. What I'm reading suggests cryo will reduce R&P wear by making them harder at the expense of becoming more brittle? It seems like it's the shock loading from snatching tyres that killed the R&P so will cryo even help with this?
