It only took a new snap ring from the Miata dealer. No grinding etc.

The hardest part was finding the specs for the bearing preload. It's not in the factory service manual. I found it in a Miata service manual and confirmed it with a RX-7 service manual. You preload the bearings so the bearing caps spread to 7.3003" - 7.3031". I set it for 7.3030" and spun the pinion with an electric motor for about 10 minutes and then reset it for 7.3010".

Running 80W-90 GL-5 conventional oil now but will change to 75W-90 GL-5 Redline synthetic in the spring.

Pulls thru the turns in 4WD like a FWD Rally car now. <img src="/forums/images/graemlins/smile.gif" alt="" />

Very controlable in de-cell too.

No dragging in turns in 2WD even with the manual hubs locked.

I will probably put the factory LSD in the rear next year. (no money now) <img src="/forums/images/graemlins/frown.gif" alt="" />
