I was able to purchase the fixed cam assembly from AutoWay Nissan in Largo, Florida. They cost me $87.00 each. I wish I had read this forum beforehand. I would had gone with manual hubs.

I experienced the same situation when replacing the brake rotor. I pulled the hub covers and the fix cam ass plastic cage was broken. A design flaw in my book.

I have the part # at home. If anyone needs it I will post it.
