You will need a 4WD spindle nut to remove the nut holding the rotor on the spindle. One will fit 1/2 and 3/4 tons, and another will fit the 1 ton models. Local parts store should have one, or most places (Autozone for one), should have it as a free tool rental. It would also be a good time to get/borrow/loan a ball-joint/u-joint press for removing/installing the front u-joints. Lots-o-rags, wheel bearing grease, brake cleaner, rotor seals, and patience should also be added to the list. While your under there, you should inspect rotors, calipers, and pads as this will be the easiest time to fix/replace them, as well as ball-joints. If the truck has any/unknown miles on it, you should replace them anyway. You will have everything torn apart that is needed to do them anyway, and if you get the balljoint press (used for pressing out u-joints) you will already have one of the two tools needed for the balljoints (the other is the balljoint adjuster sleeve socket...also available at local autopart store). It may cost a little more $$, but now IS the time to do it and will save $$ in the end. PM if you have specific questions. /forums/images/graemlins/thumb.gif
