I did the front rotors on my truck last weekend. I found the hardest part was getting the studs back in the rotor. The manual states to line up the splines of the studs and bearing housing(basically impossible). Then use a press(which I don't own) or a sledge and a drift. Well after beating on the studs for quite a while with a sledge and drift I found that on about 2 studs per side ended up being driven in far enough. So I resorted to using 5 washers and torquing down a lug nut to remove the slop. Not the easiest task when you are standing on the rotor. There was still some slop between the rotor and bearing housing. Well as it turns out when you put the wheels back on and torque to the proper ft. lbs., that will suck up any slop that is left.
On a side note the manual states that the inner wheel bearing nut has a pin on it that needs to face outboard and that the washer with the holes in it needs to be placed on this pin. It states that this is for "wheel retention". My passenger side was missing the pin yet the wheel never flew off thank god! lol
Anyways, I errored on the side of safety and was able to buy just the inboard wheel bearing nut for 14.00 at the dealership. Good Luck.
