I am assuming front , There is a very large screw on washer ( 2000 sportage ) that is dimpled into 2 grooves which you have to undimple to unscrew the nuts/washers. Be care full these nut/washers will break with too much hitting on them. Before you start find a parts store that has them in stock BEFORE you begin. Once you break one you are not going anywhere until you replace it . Anyway, after the washer/nut unscrews the hub slides off. There is more to this on the installation side ,like re-greasing bearings and setting the washer/nut tightness. Pay attention to what you are doing in dis-assembly .
No experience to do that. A mechanic man will do very good job for your Kia
Remove the tire and wheel from your 2003 Kia. Remove the axle end. Remove the wheel bearing retaining nut. Remove the wheel bearing and the wheel seal. Reverse the process to install the new wheel bearings.
