Cv joint differences explain

[TORK10]

Hi guys and gals
Sorry to come across stupid but I am currently changing out the drive shafts on a 1.4 facelift jdm Nissan march

The cv joint ends have what I can best explain looks like a large GEAR around the outer diameter of the cv joint metal cup that meets with the hub

I looked at other k11 drive shafts I have here myself from 1.3 k11 and 1ltr k11 mainly preface ones and the do not have this part

So can someone knowledgeable kindly explain to me what the purpose of this gear looking like piece is for?

WOULD I BE CORRECT IN SAYING ITS AN ABS RING?

By the way it is a facelift jdm k11 march automatic 1.4

Thanks
See here in this link the toothed gear like part I’m on about is on the left side https://autoparts.beforward.jp/detail/Transmission---Drivetrain/Drive-Shafts/PA50593654/

ABS rings are typically on the CV joint for many cars

Yep ABS ring

Cheers guys just wanted to clarify
Sound like clown now ?
I just asked because I’ve worked on several k11 over the years
Jdm and European, I’ve seen the differences between jdm-uk
And preface to facelift

And only on this facelift I’ve seen the abs ring
