1999 2wd wheel bearing preload specs
I'm still new to this truck and would like to get this correct the first time. I'm currently replacing rotors, bearings and seals on my 1999 2wd and can't find the correct procedure for packing and pre-loading the bearings. Any advice?? Thanks! Search finds lots of info on other years and 4x4...

If you don't have a bearing packer, you will need to pack them by hand.
Put a glob of wheel bearing grease in the palm of your hand. Slip the wheel bearing on your index finger like a ring with the wide end facing out. Then tap the bearing into the glob of grease until you see it coming out the other side. When you see it come out turn the whole bearing, don't just rotate it on your finger, and repeat the procedure until the whole bearing has grease coming out the other side. Repeat this for the other bearings.
place the nut on the spindle and tighten it by hand until it won't go anymore. Spin the rotor or drum a few times back and forth and then tighten the nut come more by hand. This insures that the bearings are seated in their races. Do it a couple of times until you can't get it any tighter by hand.
Now tighten the nut ¼ turn, no more than 16 foot-pounds. If you have a castellated nut, line it up with the hole going through the spindle. Install a NEW cotter pin and fold it over. If you have a retaining ring, place it on the nut and install the cotter pin. Never reuse the old cotter pin and make sure you do install it. Basically this is the only thing holding the front wheel on.
