'18 Spec Miata Cahmpionship

I wish someone would admit why they did the machining on the cages. It was done for some reason and it is either to make assembly easier or to make the car go faster......or maybe both.

I do understand how bigger balls would help you pass 20 cars and get to the front, but I digress.

I would agree.. there is some reason the parts were made different. It could be a totally legit reason...but just explain why they differ.

There is no logic case that I can see to set up a fixture on a mill or a grinder to machine this opening bigger or to have someone hand grind them. I don't see it improving the part for any normal use case. The axle would come pre-assembled and greased so the end user would never see if they made it look better or different. I certainly could be wrong but it fails the smells right test to me...

Since it looks like they were opened up marginally, only thing I can think of from a reman perspective is it makes it easier to put the stub end back together because it allow for more "angle" to get the final bearings in.

It literally took me 30-35 attempts to get the stub end back together when i rebuilt mine.

Last joint i rebuilt I found an order to put the balls back in and it was fast once you figure that out.

My bet (assumption here, obviously) is that a mass rebuilder had one of their workers realize that it would take less time to machine a cage then to fight an assembly sequence. If they are building 100 of these per employee each day, I guarantee you they are looking at ways to speed up their process to push more product out the back door. Now, it that also has a perceived performance advantage to this manufacturing aide, then the water gets murky quick.
