Wheel hub assembly center nut.

Hey everyone, I am changing the hub assembly on my 94 JGC AWD tomorrow and I am wondering what size the center nut is, it looks like a 12 point socket, but I am unsure of what size. I am trying to get all my tools around but I don't think I have any sockets that big, especially if it's metric. Any assistance is greatly appreciated. Thanks Justin

It's a 36mm (6 point). They (KD, Lisle, etc) make deep sockets specifically for removing hub nuts, just ask at the parts store. The 12 points you see is probably the retaining ring that the cotter pin goes thru.

Would I need a special socket to remove it, or would a regular deep well socket that size work?

That nut can be very difficult to get off, especially if it's been on there a while. People on this forum have reported having to use a breaker bar and pipe. If that's your situation, a regular socket may not be enough. The hub sockets are heavy duty, and rated for impact wrenches. You can find them for not too much $$$. Here's an example:
Amazon.com: TEKTON by MIT 4936 1/2-Inch Drive by 36mm Heavy Duty FWD Impact Socket: Home Improvement

Make sure you coat the hub with anti seize compound before re-installing. It will make life easier in the future.
Here's a writeup from the FAQs:

It looks simple enough, but I know from experience things are not always as they seem. I have a buddy who works on semis and he is going to let me borrow is 36 MM and huge breaker bar/giant ratchet. I appreciate all the info and look forward to getting this done tomorrow. Thanks a bunch. Justin
