I have my NSX transmission apart right now to replace the outer housing and countershaft snap ring. I did all the necessary measuring for the new mainshaft thrust shims and ordered them yesterday. I also took the lsd down to a transmission shop and had them remove one of the bearings and press on the new one. After I got home I removed the old bearing race and shim from the old outer housing and took the old shim and new bearing race in pressed them into the new housing.
After putting the outer housing back on the inner housing and torquing it down to check the preload on the diff I realized I had no way of measuring the actual torque required to spin the diff without a special tool. I put the intermediate shaft in the differential and tested it by hand...it spun freely with just a bit of resistance, but no way of knowing if it was within the 16-28 in.lb. spec. that the shop manual calls for.
So my question, am I alright with this or do I really need to find a way to accurately measure this torque value? Not that it really matters, but this is not a track car, just a daily driven street car. I doubt it will ever see track time.
