Front Hub torque specs for a 91 GMC 4x4

[GerryK61]

Hello all!

I'm new to Off-Road.com.
I have to replace my front Hubs on my 91 GMC 4x4. I hear a grinding sound coming from the front. So I decided with 160K on the frontend I'm going to replace hubs, Brake calipers and pads & CV shafts and go with steel braided brake lines.
I have 2 questions & hope you guys can help me with.

(question 1) Does anyone know the size of the CV shaft nut that holds the hub on the CVshaft? I have to purchase a socket & it looks to me about 1 3/8 Or is it metric?

(question 2) What are the torque specs for the front hub nut?
I have looked online and see specs from 59ftlbs to 160ftlbs.
I can't seem to find a good service manual where I'm located.

Thx very much & I hope you guys can help out

its big. i hodge podged socket and welded a long bar to it to do mine.

pretty much as tight as you can get that nut will be plenty good
