Here's a general overview of the process. This is not a complete, step-by-step guide, and variations may exist depending on your specific Beetle's model and trim. Always consult a repair manual specific to your vehicle's year and model for precise instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Tools you'll likely need:
* Jack and jack stands: Essential for safely lifting the car. Never work under a car supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* Lug wrench: To remove the wheel.
* Socket set and wrenches: Various sizes will be needed.
* Torque wrench: Crucial for tightening bolts to the correct specification.
* Ball joint separator: To separate the ball joint from the control arm.
* Tie rod end separator: To separate the tie rod end from the steering knuckle.
* Press or bearing puller: To remove the old bearing from the hub. A press is ideal but a puller can work.
* New front wheel bearing (and any necessary seals): Make sure you get the correct part for your vehicle.
* Penetrating oil: To help loosen rusted or seized components.
* Grease: For repacking the new bearing.
* Clean rags: To keep things clean and prevent contamination.
General Steps (Consult your repair manual for precise details):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Raise the vehicle using the jack and securely support it with jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Disconnect Components:
* Brake caliper: Carefully remove the brake caliper and secure it out of the way using a wire or bungee cord to prevent it from hanging by the brake line.
* Ball joint: Separate the ball joint from the control arm using a ball joint separator.
* Tie rod end: Separate the tie rod end from the steering knuckle using a tie rod end separator. Be sure to mark the position of the tie rod end before disconnecting, to help with reassembly.
4. Remove the Hub Assembly: Once the ball joint and tie rod end are disconnected, the hub assembly should be able to be removed. This might require some gentle persuasion.
5. Bearing Removal: This is the trickiest part. You'll need a press or bearing puller to remove the old bearing from the hub assembly. Be careful not to damage the hub.
6. Bearing Installation: Carefully install the new bearing onto the hub using a press. Ensure it's seated correctly.
7. Reassembly: Reassemble everything in reverse order, paying close attention to the order of parts. Tighten all bolts to the correct torque specifications as per your repair manual.
8. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
9. Check Alignment: After reassembly, it's highly recommended to have your wheel alignment checked by a professional.
Important Considerations:
* ABS Sensor: The ABS (Anti-lock Braking System) sensor may be attached to the hub assembly. Handle it with care and be sure to reconnect it correctly.
* Torque Specifications: Failure to tighten bolts to the correct torque specifications can lead to component failure and safety hazards. Use a torque wrench.
* Wheel Bearing Type: There are different types of wheel bearings (e.g., sealed vs. serviceable). Ensure you get the correct replacement part for your vehicle.
Again, this is a simplified overview. Refer to a repair manual specific to your 1999 Volkswagen Beetle for detailed instructions, diagrams, and torque specifications. If you're not comfortable with this level of car repair, it's best to take your car to a qualified mechanic. A poorly done job can be dangerous.
