    I'm trying to change the driver side hub assembly on my 05 z71 5.3. I got the three bolts out of the back but I dont have the right size socket for the nut in the center

    anyone know what size it is?

    Looks like bigger that 1 1/4 smaller than 1 1/2

    picked up a set of deep well sockets. It was a 36 mm

    Anyone know the torque spec for the nut that goes on the spindle??
