How do you replace rear wheel bearings for a 2003 kia Rio?

Answer 1

pretty simple really. Rear Notes Removal 1. Raise the rear of the vehicle and support it with a safety stands. 2. Remove the wheel and tire. 3. Remove the hub cap. 4. Use a small cape chisel to raise the staked edge of the lock nut. Notice: Use care not to damage the groove and threads of spindle. 5. Remove the drum, washer and bearings as an assembly from the spindle. Notice: If it is difficult to remove the brake drum, increase the shoe clearance. 6. Remove the rear brake shoe assembly and brake pipe. 7. Remove the sensor rotor by using SST (for ABS). 8. Remove the bearing oil seal. Discard the seal. 9. Remove the inner bearings from the bearing hub. Notice: If the bearings are to be reused, they should be tagged so that they can be installed in their original positions. 10. Remove the inner and outer bearing outer races by using SST. 11. Remove the wheel speed sensor (for ABS). 12. Remove the spindle attaching nuts. 13. Remove the backing plate and then support the backing plate with the wire, and remove the spindle. 14. Remove the serration bolt by using a press. Notice: * Do not remove the serration bolt if it is not necessary. * Do not reuse the serration bolt if it is removed once. Inspection Bearing Check the following and replace if necessary. 1. Abnormal wear, damage or seizure of bearing. Notice: Replace the bearing as a set (inner and outer races). 2. Damaged hub cap. 3. Wear or rust of oil seal's contact surface. 4. Crack or damage of rear hub spindle. Brake drum 1. Wear or damage on the brake drum. Notice: Remove the minor rust with a sandpaper. Installation 1. Install new serration bolts by using a press. 2. Install wheel speed sensor (for ABS). 3. Install the backing plate. 4. Install the spindle attaching nuts. Tightening torque: 32 - 45 ft. lbs. (43 - 61 Nm, 4.4 - 6.2 kg-m) 5. Tighten the wheel speed sensor (for ABS). Tightening torque: 13 - 19 ft. lbs. (17.6 - 26.5 Nm, 1.8 - 2.7 kg-m) 6. Install the rear brake assembly and brake pipe. 7. Install the outer bearing race by using a hammer. Notice: Tap in until the outer race is fully seated in the hub. 8. Position the inner bearing in the bearing hub. 9. Lubricate the oil seal lip with a lithium grease. 10. Install an oil seal. 11. Install the sensor rotor by using a flat plate to press it in (For ABS). Notice: o Use a new oil seal, and coat the lip with grease in the middle of the right halfshaft. o Do not hit the oil seal directly with a hammer. 12. Completely fill the area shaded in the figure with a lithium grease. 13. Position the brake drum bearings and hub assembly on the spindle. 14. Keep the drum which is centered on the spindle to prevent a damage to the oil seal and spindle threads. 15. Install the outer bearing. 16. Install the washer. 17. Install new lock nut. 18. Adjust the bearing preload. Bearing Preload: 5.6 - 8.6 ft. lbs. (0.65 - 0.98 Nm, 6.5 - 10 kg-cm) 19. Fix lock nut to the groove firmly. Inside loosening of lock nut: more 14.4 ft. lbs. (19.6 Nm, 2 kg-m) 20. Install hub cap. Bearing preload 1. Make sure the parking brake is fully released. 2. Remove the wheel and tire assembly. 3. Remove the grease cap. 4. Rotate the brake drum to make sure there is no brake drag. 5. Seat the bearings by tightening the nut after raising the nut tap. Tightening torque: 18 - 22 ft. lbs. (25 - 29 Nm, 2.5 - 2.9 kg-m) 6. Loosen the nut slightly until it can be turned by hand. Before the bearing preload can be set, the amount of seal drag must be measured and added to the required preload. 7. Use a pull scale and measure the oil seal drag. 8. Pull the scale squarely. Take the oil seal drag value when the wheel hub starts to turn, and record it. 9. Add the oil seal drag value in the previous step to the specified value of 0.6 - 1.9 lbs. (2.6 - 8.5 N, 0.26 - 0.87 kg) . This is regarded as the standard bearing preload. 10. Turn the nut slowly to adjust to the standard bearing preload while checking with the pull scale. 11. Firmly fix the lock nut to the groove. 12. Install the hub cap. 13. Install the wheel and tire assembly. Tightening torque: 65 - 87 ft. lbs. (88 - 118 Nm, 9.0 - 12.0 kg-m)
