Drivetrain - Front Wheel Bearing Preload Procedure

SOURCE: Kia Technician Times

TITLE: Front Wheel Bearing Preload

APPLIES TO: Rio

SERVICE TIP:






When servicing front wheel bearings on Rio models, it is critical to have the correct preload on the bearings. Kia calls out SST 0K130 322 020 for use with a pull scale, however this SST (arm) is not available. The specifications are listed for use of a pull scale or a torque wrench. KMA recommends using an inch-pound torque wrench and the following procedure. (procedure requires the use of Special Service Tool 0K130 331 016)

1. With steering knuckle removed from the vehicle and hub removed from the knuckle, clamp SST-0K130 331 016 in a bench vice.
2. Install knuckle with rear bearing onto SST.
3. Install spacer and outer bearing onto SST.
4. Install the SST bushing and nut, then torque to 116-173 lb-ft (157-235Nm).
5. Remove from the bench vice and clamp the knuckle in the vice so that the SST can turn in the bearings.
6. Using an inch-pound torque wrench, turn the SST to check the preload. Preload specification is 2.17-10.41 lb-in (.25-1.17 Nm).

If preload is not within specification, replace the spacer and recheck preload.
