Safety Precautions
Before starting any work on your vehicle, it’s crucial to take necessary safety precautions. Wear appropriate safety gear, including gloves and safety glasses. Park the vehicle on a level surface, engage the parking brake, and chock the wheels opposite the one you’ll be working on.
Step-by-Step Instructions
1. Remove the Wheel
Use the socket wrench to loosen the lug nuts on the affected wheel but do not remove them completely. Raise the vehicle using a jack and place a jack stand for stability. Remove the lug nuts and pull the wheel straight toward you to detach it.
2. Remove the Brake Caliper
Unbolt the brake caliper bolts using the socket wrench. Carefully lift the caliper and secure it to the suspension or a nearby surface using a bungee cord or wire. Do not let the caliper hang by the brake hose.
3. Remove the Brake Rotor
Remove the two bolts holding the brake rotor in place. Use a rubber mallet to gently tap the rotor and loosen it from the hub. If the rotor is stuck, you may need to use a puller.
4. Remove the Axle Nut
Using the 32mm axle nut socket, loosen the axle nut but do not remove it entirely.
5. Remove the Tie Rod End (Optional)
If necessary, remove the tie rod end by unbolting it from the steering knuckle. This step may vary depending on your Hyundai Elantra model.
6. Separate the Knuckle from the Strut
Use the socket wrench to remove the bolts connecting the knuckle to the strut. Carefully pry the knuckle away from the strut using a pry bar or a large screwdriver.
7. Remove the Old Wheel Bearing
Using the wheel bearing puller, attach it to the old wheel bearing and tighten the puller bolt to remove the bearing from the hub. If the bearing is particularly stubborn, use a slide hammer.
8. Install the New Wheel Bearing
Apply grease to the inside of the new wheel bearing. Carefully insert the new bearing into the hub and use the wheel bearing puller to press it in place. Ensure the bearing is fully seated.
9. Reassemble the Knuckle
Place the knuckle back onto the strut and tighten the bolts to the specified torque using the torque wrench.
10. Reattach the Tie Rod End (Optional)
If you removed the tie rod end, reattach it to the steering knuckle and tighten the bolts.
11. Install the Brake Rotor
Place the brake rotor onto the hub and tighten the bolts to the specified torque.
12. Reinstall the Brake Caliper
Reposition the brake caliper onto the rotor and tighten the caliper bolts to the specified torque.
13. Install the Wheel
Place the wheel back onto the hub and tighten the lug nuts by hand. Lower the vehicle and fully tighten the lug nuts using the torque wrench to the specified torque.
Tips for Success
- Use high-quality replacement parts.
- Apply grease to all moving parts.
- Tighten all bolts and nuts to the specified torque.
- If you encounter any difficulties, do not hesitate to consult a professional mechanic.
