What is the 2005 kia rio front axel nut torque ???

Over torque of the spindle locknut and improper grease packing are the main failures I would think. I did numerouse brake jobs on mine and allways used new seals cleaned out the bearings and repacked them dont forget to fill in the inside of the hub with more grease where needed. A new spindle lock nut is a must 75 cents at the dealer i had no luck finding them at the local parts stores. Remember new bearings and and races must be used press the races in properly. There is a special tool drag seal meter to use I dont have one so i would torque the nut to 20 FT LBS while turning the hub back and forth untill it was seated then back off the nut till loose and re torque the nut to 3-5 foot LBS stake it and have never had an issue hopefully this help you out

when you buy the new bearing it will have everything included

Three bolts are 70 lbs,could be 120+/-.

remove tire
remove axle nut
remove 3 bolts holding hub in
sometimes may need to hit hub with hammer after all bolts out to get it to release

you will need a big socket to remove the axle nut--about 20 mm or so. Other than that, I don't think so. Procedures from autozone.com below. it doesn't mention having to press bearing into hub.

   Wheel bearing into hub Wheel hub to steering knuckle and driveshaft; torque bolts to 41 ft. lbs. (56 Nm) ABS sensor; torque to 6 ft. lbs. (8 Nm) Brake rotor and caliper New flanged hub nut; torque to 134 ft. lbs. (182 Nm)
   

TOOLS YOU NEED IS 35 METRIC SOCKET FOR AXLE NUT.USE 6 POINT SOCKET.DONT USE 12 POINT SOCKET.COULD DAMAGE AXLE BOLT EDGES.MAKING IT HARD TO GET OFF.YOU NEED A TORQUE WRENCH WITH THE RANGE OF 200 FT LBS TORQUE.YOU NEED 1/2 BREAK BAR.AND A HUB PULLER.NOW TO LOOSEN AXLE NUT.BEST TO LEAVE TIRE ON WITH CAR WEIGHT ON GROUND TO LOOSEN THE AXLE.BECAUSE ITS GOT 192 FT LBS TORQUE.HARD TO LOOSEN WITH TIRE OFF.192 FT LBS TORQUE IS WHAT YOU TORQUE IT AT.BESURE TO READ INSTRUCTIONS TO NEW HUB BEARING ASSEMBLY. YOUR AXLE NUT TORQUE WILL BE DIFFERENT IF YOU GET A NEW GREY NUT.BECAUSE NUT STRENGHT WILL BE DIFFERENT.IF YOU GET A BLACK NUT WHICH IS HARDER STEEL TORQUE WILL BE 192 FT LBS.YOU NEED A 13 METRIC SWIVEL SOCKET TO GET HUB BEARING BOLTS OFF THEY WILL BE IMPOSSIBLE TO REACH WITH OUT IT.HUB BEARING BOLTS TORQUE IS 62 FT LBS

clean all the grease if there is any out of the hub, turn the hub over and using a drift and hammer strike the shell from the back edge working around the shell as you go, should not take too much to remove it but you will need a bit more than a tap with the hammer.
Hope this has helped you

Here's the steps....getting some pics for you....hang on a minute or two.

Front Hub Removal & Installation To Remove:

1. Remove steering knuckle.
2. Using a suitable slap hammer, remove wheel hub assembly.
3. Using a suitable bearing press, remove outer bearing, oil seal, outer bearing race and preload spacer.
4. Remove inner oil seal, inner wheel bearing and inner bearing race.

NOTE: It is not necessary to remove dust cover (back plate).
To Install:

1. Using a suitable bearing press, install bearing races in steering knuckle.
2. Pack the bearings and hub area with lithium grease.
3. Install inner bearing in steering knuckle.
4. Lubricate lip of NEW inner seal and press seal into knuckle.
5. Install preload spacer into bore.
6. Install outer bearing into bore.
7. Lubricate lip of NEW outer seal and press seal into knuckle.
8. Using an appropriate tool, support inner wheel bearing and press wheel hub into knuckle with a force of 2500kg.
9. Install NEW inner seal.
10. Install knuckle assembly.

Remove the brake caliper
Remove the disc, (rotor)
Remove the 34mm nut on the axel shaft
Remove the three (3) bolts from the back side
You will need a wheel puller (three jaw will work well)
Place the puller over the hub and tighten, this will push the shaft out of the hub. Now you have to pull the hub assy. out of the mounting bracket. I found hitting each side,of the hub with a lead hammer to work well. Don't forget to disconnect the ABS senser on the back side of the hub assy.
Do not over tighten the 34mm axel nut when you install the new assy. If you use an impact whrench on it you will damage the bearing.

112 to 174 ft lbs
