Step 2: Prepare the Vehicle

Safety is crucial when working on your vehicle.

1. Park on a Flat Surface: Ensure the car is on a flat surface to prevent rolling.
2. Loosen Wheel Nuts: Slightly loosen the wheel nuts while the car is still on the ground.
3. Lift the Vehicle: Use a jack to lift the front of the car and secure it with jack stands.
4. Remove the Wheel: Take off the wheel to access the brake assembly and hub.

Step 3: Remove the Brake Components

To access the wheel bearing, you need to remove the brake components.

1. Remove Brake Caliper:

   • Unscrew the caliper bolts using the socket set.
   • Hang the caliper on a support to avoid stress on the brake line.

2. Remove Brake Disc:

   • If necessary, remove any screws or clips that hold the brake disc.
   • Take off the brake disc to gain access to the hub.

Step 4: Remove the Hub and Wheel Bearing

Now you can proceed to remove the old wheel bearing.

1. Remove Hub Nut:

   • Use a socket to remove the hub nut. It may require a lot of force, so ensure you have a good grip.

2. Pull Off the Hub:

   • If the hub is stuck, gently tap it with a hammer or use a bearing puller.
   • Be careful not to damage any surrounding components.

3. Remove Wheel Bearing:

   • Use a bearing puller if available. Otherwise, tap it out gently using a hammer and appropriate tool.
   • Clean the area where the new bearing will be installed.

Step 5: Install the New Wheel Bearing

Installing the new wheel bearing is crucial for proper functionality.

1. Lubricate the Bearing: Apply a small amount of grease to the new bearing.
2. Press in the New Bearing:
   • Align the new bearing with the hub and press it in carefully.
   • Ensure it is seated properly and flush with the hub.

Step 6: Reassemble the Components

Once the new bearing is in place, reassemble all the components.

1. Replace the Hub:

   • Place the hub back onto the spindle.
   • Tighten the hub nut to the manufacturer’s specifications.

2. Reattach Brake Disc and Caliper:

   • Reinstall the brake disc and caliper in reverse order of removal.
   • Ensure all bolts are tightened securely.

3. Reattach the Wheel:

   • Put the wheel back on and hand-tighten the nuts.

Step 7: Lower the Vehicle and Final Checks

After reassembly, you can lower the vehicle.

1. Lower the Car: Carefully remove the jack stands and lower the vehicle.
2. Tighten Wheel Nuts: Once on the ground, fully tighten the wheel nuts in a crisscross pattern to ensure even pressure.
3. Test Drive: Take the car for a short test drive to ensure everything is functioning correctly.

Conclusion

Replacing the front wheel bearings on a VW Golf 4 is a manageable DIY task that enhances vehicle safety and performance. Remember to use quality parts, follow safety precautions, and check all components during reassembly. If you're uncertain at any point, consider consulting a professional mechanic. Happy driving!
