HUB BEARING REPLACEMENT

2001 Hyundai Elantra • 4 cylinder 2WD Automatic •

How do I remove and replace broken wheel bearings on a 2001 elantra? I just replaced my passenger side axle and removed the hub, doing so, the bearings actually fell out when I removed the hub, figured I should replace that as well. How hard is it to do so and what does it entail?

You need a press and press jig. The new bearing is a press fit, here's how. Removal

1. Remove steering knuckle and hub assembly. See STEERING KNUCKLE. Install Hub
Remover & Knuckle Arm Bridge Adapter on steering knuckle. See SPECIAL TOOLS table.
See Fig. 6.

2. Remove brake disc from hub. Separate hub from steering knuckle. Install Hub Bearing
Remover to hub. See SPECIAL TOOLS table. Using bearing puller, remove outer bearing
inner race from hub.
3. Remove seal and inner bearing inner race from steering knuckle. See Fig. 7. Elantra, Santa Fe,
Sonata, Tiburon and XG300 models use a snap ring that must be removed before inner bearing
can be removed. A Front Axle Base is also used to hold knuckle in position while bearings are
being removed. See SPECIAL TOOLS table.
4. On all models, use Hub Outer Bearing Remover to remove outer races from steering knuckle.
See SPECIAL TOOLS table. If either race requires replacement, replace complete bearing.

Installation

1. Use handle with Hub Bearing Installer and base to install bearing races. See SPECIAL
TOOLS table. Ensure races are fully seated.
2. Install brake disc on hub. Pack wheel bearings with grease. Install outer bearing into knuckle.
Apply grease to seal lip and hub contact surface.
3. Use correct Seal Installer and handle. See SPECIAL TOOLS table. Install outer seal until seal
is even with steering knuckle end surface. Install inner bearing into steering knuckle.
4. Using hub remover/installer, mount hub to steering knuckle. See Fig. 9. Tighten nut on hub
remover/installer tool to 170 ft. Lbs. (230 N.M.).

5. Rotate hub to seat bearing. Using an INCH-lb. Torque wrench, measure hub starting torque. See
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.
6. Using dial indicator, move hub in and out and measure axial play. Check assembly procedure if
movement exceeds specification. See WHEEL BEARING under ADJUSTMENTS &
INSPECTION. Remove hub remover/installer.
7. Using seal installer and handle, install inner seal until seal contacts bearing outer race. Coat
inner seal lip with grease. To complete installation, reverse removal procedure.
