Tools You'll Likely Need:
* Jack and jack stands: Essential for safely lifting the truck. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheel.
* Hammer and punch: For removing and installing components.
* Socket wrench set and various sockets: Including those for the axle nut, caliper bolts, and other fasteners.
* Bearing race and seal installer/remover: These tools make the job significantly easier and less prone to damage. Improper removal can damage the axle housing.
* Torque wrench: Crucial for tightening components to the correct specifications. Incorrect torque can lead to premature bearing failure.
* Penetrating oil: To help loosen rusted or seized bolts.
* New rear wheel bearings and seals: Get the correct parts for your specific Ranger model.
* Grease: For packing the new bearings.
* Clean rags and shop towels: To keep things clean.
* Safety glasses and gloves: Protect yourself from injury.
General Steps (Consult your repair manual for specifics):
1. Safety First: Secure the vehicle with jack stands and wheel chocks. Engage the parking brake.
2. Remove the Wheel: Remove the lug nuts and wheel.
3. Remove the Brake Caliper and Rotor: Remove the caliper bolts and carefully hang the caliper out of the way. Support it with a bungee cord or wire to prevent damage to the brake line. Remove the rotor.
4. Remove the Axle Nut: This is often very tight. Use a breaker bar and potentially a socket extender for leverage. The nut may be left-hand threaded, so be careful to turn it in the correct direction. Mark the nut and axle so you can reinstall it in the same orientation.
5. Remove the Axle Flange: Separate the axle flange from the hub. This may require a slide hammer or other specialized tools depending on how seized it is.
6. Remove the Old Bearing and Seal: This is where the bearing race and seal puller are essential. Attempting this without the right tools can easily damage the axle housing.
7. Clean the Axle Housing: Thoroughly clean the axle housing to remove any old grease, debris, or rust.
8. Install New Seal: Carefully install the new seal using the appropriate tool.
9. Pack the New Bearing with Grease: Thoroughly pack the new bearing with grease.
10. Install the New Bearing: Carefully install the new bearing using the appropriate tool.
11. Reassemble: Reinstall the axle flange, axle nut, rotor, caliper, and wheel, tightening everything to the correct torque specifications (consult your repair manual).
12. Check for Play: After reassembly, check for any play in the wheel. If there is play, you'll need to troubleshoot and correct the issue.
Important Considerations:
* Left-Hand Threads: The axle nut may be left-hand threaded. Turning it the wrong way could damage the threads.
* Torque Specifications: Using the correct torque settings is critical to avoid damage and ensure proper function.
* Bearing Preload: The bearing must have the correct preload. Too much or too little can lead to premature failure.
* Repair Manual: A repair manual specific to your 1997 Ford Ranger is absolutely essential. The steps and torque specifications will vary slightly depending on your model.
