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.
