Take a pair of channel lock pliers and while spinning the hub, tighten the nut fairly snug to seat the bearings. Then back the nut off, tighten it finger tight & insert the cotter pin in the hole. If the hole doesn't line up, the back the nut off until it does. If it's tight it'll burn up the bearing.
What is the torque on the front wheel hub nut? It can't be much as it came off the spindle with little force.
If you want the exact directions from Chevy--while rotating wheel, tighten spindle nut to 12 ft lbs. Back off the nut one flat & insert cotter pin. If slot & pin don't line up, back off the nut an additional 1/2 flat or less as required to insert the cotter pin.
Does the Differential Cover bolts have any torque spec and any tightening down bolt sequence?
It probably does, but no one uses it. Just tighten them like and other 1/2" bolt. Make up your own sequence, it won't matter.\
