Gathering the Necessary Tools

• Socket set (metric): A complete metric socket set is essential, ranging from small sizes for bolts to larger ones for the axle nut. You’ll need various sizes to handle all the fasteners involved in removing and reinstalling the axle.
• Torque wrench: This is crucial for tightening bolts and nuts to the manufacturer’s specified torque. Using an incorrect torque can lead to damage to the parts or even unsafe conditions.
• Wheel chocks: Always secure your vehicle with wheel chocks to prevent accidental movement. Safety should be your top priority while working under your vehicle.
• Jack and jack stands: Safely raise the vehicle using a sturdy jack and secure it with jack stands before starting any work. Never work under a vehicle supported only by a jack.
• Drain pan: You’ll need a drain pan to catch the gear oil that will drain when you remove the axle.

Sourcing the Replacement Seal and Other Parts

The correct replacement rear axle seal is crucial for a successful repair. Using an incorrect seal can result in leaks and damage to other parts. It is always advisable to purchase genuine Ford parts or high quality alternatives from reputable auto parts suppliers. Confirm the part number before purchasing to ensure compatibility.

• Rear Axle Seal: Always ensure you have the correct part number for your specific 2000 Ford Explorer model. Using an incorrect seal will result in a failed repair.
• Gear Oil: You’ll need fresh gear oil of the correct viscosity (check your owner’s manual) to refill the differential after the repair.
• New Axle Nut: The axle nut may be damaged during removal. Replacing it ensures a proper seal and prevents future problems.
• Seal Installer Tool: This specialized tool helps install the new seal without damaging it. Improper installation is a common cause of seal failure.

Removing the Old Rear Axle Seal

This section will guide you through the meticulous process of removing the old, damaged rear axle seal. It’s crucial to follow these steps carefully to avoid damaging the axle housing or any other components. A damaged axle housing can be expensive to repair, so take your time and be precise.

Preparing the Axle for Seal Removal

1. Securely jack up the vehicle and place it on jack stands.
2. Remove the rear wheels.
3. Remove the axle nut. This will require a significant amount of torque; an impact wrench may be helpful.
4. Carefully remove the axle shaft. You may need to gently tap it with a hammer to loosen it.
5. Clean the area around the axle housing where the seal is located.

Extracting the Old Seal

Removing the old seal requires a delicate touch to prevent damage to the axle housing. Using the correct tools and techniques is essential for a successful seal removal. A damaged axle housing could necessitate a costly repair or even axle replacement.

1. Use a seal puller or a suitable improvised tool to gently remove the old seal.
2. Inspect the axle housing for any damage. Any grooves or damage to the housing seat may require additional repair or replacement.
3. Thoroughly clean the axle housing seat to ensure a proper seal for the new part.

Installing the New Rear Axle Seal

Installing the new seal requires precision and care to ensure a proper fit and prevent future leaks. Using the correct tools and techniques is critical here. A poorly installed seal will almost certainly lead to leakage and necessitate repeating the whole process.

Preparing the New Seal and the Axle Housing

• Inspect the new seal for any defects before installation.
• Lubricate the new seal’s lip with a compatible lubricant (check your owner’s manual or consult an auto parts expert).
• Ensure the axle housing seating surface is clean, smooth, and free of any debris.

Installing the New Seal

Installing the seal correctly is paramount to the success of the repair. Using a seal installer tool will help you avoid damage to the new seal. Forcing the seal in without the proper tool can easily damage the seal rendering it useless.

2. Ensure the seal is seated correctly and flush with the axle housing.
3. Inspect the seal again to ensure its proper installation.

Reassembling and Testing

This final section covers reassembly, refilling the differential with gear oil, and testing for leaks. Proper reassembly is crucial to ensure the successful completion of the repair. Remember to follow the manufacturer’s specified torque values for all bolts and nuts to prevent damage.

Reassembly of the Axle

1. Carefully reinstall the axle shaft, ensuring it seats correctly.
2. Tighten the axle nut to the manufacturer’s specified torque. Consult your owner’s manual for the correct torque specification.
3. Reinstall the wheels and lower the vehicle.
4. Fill the differential with the correct type and amount of gear oil, as specified in your owner’s manual. Overfilling or underfilling can cause problems.

Testing for Leaks

After refilling the differential with gear oil, it is crucial to check for leaks. Regularly inspect the area for leaks to ensure the seal is working properly and no further repairs are required. A leak indicates the repair was unsuccessful and requires attention.

1. Start the vehicle and run it for a short period. Check for any leaks around the seal.
2. Inspect the area around the seal for leakage after a short drive. Check again after 24 hours.
