The socket you are probably talking about is to push out the wheel bearing if it is seized into the knuckle but you can do the same thing with a socket slightly bigger than the bolt head and an extension like 6" and you just back all 4 bolts out about a half inch and then you put the socket and extension over one of the bolts and against somewhere on the axle then start the truck and use the power steering to push the wheel bearing loose. Hopefully that makes sense I'm sure there are videos if not and you can also use the same idea and method on a rotor that doesnt want to come off. Works great though. Other than that I would recommend a quality bearing like a Timken or factory otherwise they seem to wear quick which brings me to anti seize use some incase you have to pull the wheel bearing off again later down the road. Also a good time to check front axle Ujoints and replace if needed, I recommend Spicer joints. Big axle nut is 1-11/16". I think that covers it all.
