Yup, just checked and it's 36mm

Also have a good/long torque wrench when you tighten it. Torque spec is like 177 ft lbs

You'll need a good long breaker bar to break the old ones loose, driver side was easy for me.. pass side I had to stand on my "extension" until it came free.

Luckily it's the same as my '89 GMT400 K1500 was and I saved the socket so it worked fine on my '07 Hoe after I dug it out of the bottom of the socket drawer in the tool box. :)

Unless you have air tools and a good impact gun ;)

Indeed it was 36mm. I did the replacement today. All went well and the noise is gone. However, I have a question for those of you who have done a hub job. I read the torque specs are 177 Ft/lb of torque on the axle nut. My torque wrench, unfortunately, only goes to 155. So I torqued it to 155 and then put by breaker bar on to the socket and move it a slight bit more. So I'm tighter than 155, to 177? Probably, if not further. Is there a risk going too tight with this? I don't really want to go buy a torque wrench that goes to 177 but knowing I might have over tightened it with a breaker bar worries me. Not sure what could go wrong. I didn't go crazy, just gave it a little pull from the breaker.

Also, those hub nuts (3) that hold the assembly to the knuckle are supposed to be torqued to 133. Holy cow that's hard in such a small space to get them that tight. I ended up putting a open-end wrench on each and hitting the wrench with my rubber mallet multiple times till it didn't give. The bolts are only a 15 and rathe soft. I need to get back under there and torque them properly but my current torque wrench is a bit too long to make this work. Need to buy a smaller one.

You're good at 155 + a yank. 133 is nuts on those 3 15mm, imo. Just get em good and tight. Check on them in a while if you need to ease your mind.

Sorry for the update mods.

I just wanted to say that for my 2001 Yukon, the nut is 35mm. It seems that if you're using an aftermarket axle, it will come with a 36mm nut.

A 36mm socket will probably work, but I don't like living that wild.

Yes, I have removed 35mm nuts with a 36mm socket before.
