Tools You'll Need:
* Jack and jack stands: Absolutely essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheel.
* Socket wrench set (metric): Various sizes, including those for axle nuts, CV axle bolts, and possibly other fasteners.
* Ratcheting wrench: Makes things easier.
* Ball joint separator (pickle fork or ball joint press): To separate the ball joint from the steering knuckle. A ball joint press is preferred to avoid damage.
* Hammer: May be needed in conjunction with the ball joint separator.
* Penetrating oil (PB Blaster or similar): Helps loosen rusted bolts.
* CV axle puller (optional but highly recommended): Makes removing the axle much easier and reduces the risk of damage.
* New drive axle: Make sure to get the correct replacement part for your S-10.
* Torque wrench: Crucial for proper tightening of bolts and nuts.
* Grease: For the new CV joint.
* Safety glasses and gloves: Protect yourself.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Raise the front of 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 the Brake Caliper: Use a socket wrench to remove the caliper mounting bolts. Carefully support the caliper with a bungee cord or wire to prevent it from hanging by the brake line.
4. Disconnect the ABS Sensor (if applicable): Some models have an ABS sensor on the knuckle. Carefully unplug the sensor.
5. Disconnect the Ball Joint: Use the ball joint separator to separate the lower ball joint from the steering knuckle. This is often the most difficult part of the job. Apply penetrating oil liberally beforehand.
6. Remove the Axle Nut: Use a socket wrench to remove the large nut securing the axle to the wheel hub. This nut will likely be very tight.
7. Separate the Axle from the Hub: Once the nut is removed, the axle should slide out of the hub. A CV axle puller can be invaluable here.
8. Disconnect the Axle from the Transmission: The inner CV joint is usually held in place by a retaining clip. Remove this clip. The axle should then be able to slide out of the transmission.
9. Install the New Axle: Reverse the removal process to install the new axle. Be sure to properly lubricate the CV joints with grease.
10. Reconnect Everything: Reinstall the axle, the hub, the ball joint, the brake caliper, and the wheel. Tighten all bolts and nuts to the manufacturer's specified torque settings (consult your repair manual).
11. Lower the Vehicle: Carefully lower the vehicle using the jack.
12. Test Drive: Test drive the vehicle to ensure the new axle is working correctly.
Important Notes:
* ABS Sensor: Be extremely careful with the ABS sensor if your vehicle has one. Damaging it can lead to ABS system problems.
* Torque Specifications: Using a torque wrench and adhering to the manufacturer's torque specifications is critical to prevent damage.
* Difficulty: This is not a beginner's job. If you're unsure about any step, seek the help of a qualified mechanic. Improper installation can lead to serious damage or injury.
* Parts: Make sure you get the correct replacement axle for your specific S-10 model. There are variations.
This is a general guide; the specific steps might vary slightly depending on your particular S-10 model. Again, always consult a repair manual specific to your vehicle. It's the best way to avoid mistakes and ensure a safe and successful repair.
