can be removed. A Front Axle Base is also used to hold knuckle in position while bearings are
being removed. See SPECIAL TOOLS table.

Fig. 9. Starting torque should be 12 INCH lbs. (1.3 N.M) or less on Accent and Tiburon. On
Elantra, Santa Fe, Sonata and XG300, starting torque should be 16 INCH lbs. (1.8 N.M) or less.
