Tools You'll Need:
* Jack and Jack Stands: Safely lift the van and secure it. Never work under a vehicle supported only by a jack.
* Lug Wrench: To remove the wheel.
* Wheel Chocks: To prevent the van from rolling.
* Socket Set and Wrenches: Various sizes will be needed, likely including metric sizes.
* Ball Joint Separator (Pickle Fork or similar): To separate the ball joint from the steering knuckle. This is often the trickiest part.
* Hammer and Punch (or suitable impact driver): May be needed to help separate parts.
* Penetrating Oil (PB Blaster or similar): To help loosen rusted or seized bolts and parts.
* Torque Wrench: Essential for tightening bolts to the manufacturer's specifications.
* New Front Wheel Hub Assembly: Ensure you get the correct part for your vehicle.
* Replacement cotter pin (if needed).
Procedure (General Outline):
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Wear safety glasses.
2. Raise and Secure: Use the jack to lift the van, placing jack stands securely under the frame near the wheel you're working on.
3. Remove Wheel: Remove the lug nuts and carefully remove the wheel.
4. Brake Caliper Removal: You'll likely need to remove the brake caliper to access the hub. Use a suitable wrench to loosen the caliper mounting bolts. Support the caliper with a wire or bungee cord to prevent it from hanging by the brake line. Don't let the brake line hang freely, it could be damaged.
5. Disconnect the ABS Sensor (if equipped): If your vehicle has an Anti-lock Braking System (ABS), carefully disconnect the ABS sensor wire from the hub.
6. Remove the Axle Nut: This is often a large nut on the end of the axle shaft. It will be very tight, so use a breaker bar if needed. You might need to hold the rotor with a wrench to prevent it from spinning.
7. Separate the Ball Joint: This is usually the most difficult part. You'll need to use a ball joint separator to separate the lower ball joint from the steering knuckle. Apply penetrating oil generously beforehand. Work carefully and avoid damaging the ball joint or knuckle.
8. Remove the Hub Assembly: Once the ball joint is separated, the hub assembly should be able to be pulled off the spindle. There might be some resistance.
9. Installation: The installation is the reverse of removal. Ensure everything is properly aligned and lubricated. Pay close attention to the correct orientation of components like the ABS sensor.
10. Torque Specifications: Tighten all bolts and nuts to the manufacturer's specified torque using a torque wrench. This is critical to prevent premature failure and ensure safety.
11. Lower and Check: Carefully lower the vehicle. Reconnect the brake caliper and bleed the brakes (if necessary). Double check all bolts, wheel lugs etc. Test drive carefully.
Important Considerations:
* Rust and Corrosion: On a 1993 vehicle, rust and corrosion are likely to be significant factors. Use penetrating oil generously and be prepared for stubborn fasteners.
* Professional Help: If you're not comfortable with this type of repair, it's best to take your vehicle to a qualified mechanic. Incorrectly installed components can lead to serious safety hazards.
* Repair Manual: A repair manual specific to your 1993 Dodge Caravan is invaluable. It will provide detailed instructions, diagrams, torque specifications, and other essential information.
This is a general guideline. Always refer to your vehicle's repair manual for detailed instructions specific to your vehicle's year and model. Improper repair can lead to serious safety issues. If you are unsure about any step, consult a professional mechanic.
