Anyway it's basically back together, might have to dive back in to seal that if it's necessary. I hope that stops my leakage, I'm sick of adding oil to the t-case every few weeks...
You WILL leak past the splines. Trust me on this. The seal is betwen the e-brake drum and the speedo housing (yes, you are right, there is a gasket between the speedo housing and the t-case housing). But the only thing to stop 90wt from getting past the splines is the big flat washer under the nut, and it won't seal. That's why the factory puts red RTV sealant on the splines.
