Gathering Necessary Tools and Materials

• A new DAF 1335063 rear wheel hub oil seal.
• A socket set and ratchet.

• Flathead and Phillips screwdrivers.
• Pry bar or seal puller.
• Clean rags and a degreaser for maintenance.

Step-by-Step Replacement Process

1. Raise the Vehicle

Begin by ensuring that your vehicle is parked on a flat surface. Use jack stands to securely elevate the rear of your vehicle, allowing you easy access to the wheels.

2. Remove the Wheel

Using the appropriate socket from your toolkit, take off the lug nuts and remove the rear wheel. This will expose the brake drum or disc that you may need to work around.

3. Take Off the Brake Components

If your vehicle has drum brakes, you may need to remove the drum to access the hub. For disc brakes, you’ll need to remove the caliper and possibly the brake disc. Ensure you support the caliper properly to avoid strain on the brake line.

4. Remove the Hub Assembly

With the brake components out of the way, you can now access the hub assembly. Remove any retaining bolts or clips holding the hub in place. Use a pry bar if necessary to gently release the hub from its mounting.

5. Replace the Oil Seal

Once the hub is removed, locate the old oil seal. Use a seal puller or a flathead screwdriver to carefully lift the old seal out of its recess. Ensure that you clean the area of any debris or remnants of the old seal. Take your new DAF 1335063 oil seal, lubricate the outer edge with a bit of oil, and press it firmly into the hub. Ensure it’s seated evenly to avoid future leaks.

6. Reassemble the Hub and Brake Components

Place the hub back onto the axle, securing it with the appropriate bolts. Follow the steps in reverse to reattach the brake drum or disc and the wheel. Be sure to torque the bolts to the manufacturer's specifications.

Final Checks and Testing

After everything is reassembled, lower your vehicle back to the ground. Before you hit the road, check for any signs of leaks around the newly fitted seal. Take the vehicle for a short test drive to ensure everything is functioning correctly.

By following this guide, you can effectively replace your DAF 1335063 rear wheel hub oil seal, improving your vehicle's performance and prolonging its lifespan. Regular maintenance and checking for wear can help you avoid more significant repairs in the future, ensuring a safer and smoother ride.
