I need to know what size in millimeters the socket to remove the nut that attaches the wheel hub to the rear wheel knuckle is? It's a huge beast too, maybe 1.5 inches, I checked the torque spec on it and it's 181 ft-lbs. Also, where would I be able to purchase a good quality socket for this size? Thanks in advance.

36mm, the torque spec was revised to 220ft lbs

It is a common hub nut size so most auto parts stores will have one.

I had a problems with mine that was not initially fixed by re-torqueing the nuts.. turns out my old click type torque wrench is very inaccurate over about 120 lb/ft (even though is is pretty close up to about 90).

I was not even close and did not know it, so the lesson learned is to be very cautious with measurements at the extremes. My wrench (a 10+ yr old craftsman) is marked from 25 to 250 but is only close to accurate from 40 to 100. The torque rapidly falls off at high settings.

My biggest torque wrench only goes up to 150 ft-lbs. If I don't want to buy another torque wrench just for this nut then how do you guys suggest I properly tighlty this nut? The service manual says 181 ft-lbs, just to verify, now it's 220 ft-lbs?

There was a Service News article covering retorquing the hub nuts to 220ft lbs.

The socket can be purchased from Sears for $10. That's where I got mine.

The torque spec is still actually 180 lb/ft with the TSB saying you can go to 220 lb/ft to solve a single click noise that comes from some cars. I tightened mine to 220 only to find out a couple of weeks later, when the noise returned, that the wheel bearing was the root cause.
