Step-by-Step Instructions:
1. Prepare Your Vehicle:
- Engage the parking brake and turn off the engine.
- Loosen the lug nuts on the front wheel where you'll be replacing the CV axle. Do not remove the lug nuts completely at this point.
2. Raise the Vehicle:
- Use a jack to raise the front end of the car until the tire clears the ground.
- Place jack stands under the car to support it safely while you work.
3. Remove the Wheel:
- Completely remove the lug nuts and take off the front wheel.
4. Remove the Brake Caliper:
- Locate the brake caliper, usually secured to the wheel hub with two bolts.
- Use a socket wrench or pliers to loosen and remove these bolts.
- Gently pry the caliper away from the brake rotor without disconnecting the brake line. Secure the caliper out of the way using cable ties.
5. Remove the Rotor and Hub Assembly:
- Remove the brake rotor from the hub assembly.
- Locate and remove the bolts holding the hub assembly in place. Usually, there are three or four bolts on the back side of the hub assembly.
6. Remove the Old CV Axle:
- Once the hub assembly is removed, use a flat-head screwdriver to pry off the dust boot from the inboard end of the CV axle.
- Use a pry bar to pry out the CV axle from the wheel bearing.
- Slide the old CV axle out of the differential.
7. Clean the CV Axle Joint and Differential:
- Clean the CV axle joint and the mating surface on the differential using a wire brush.
- Remove any dirt, grease, or old gasket material.
8. Install the New CV Axle:
- Insert the new CV axle into the differential, ensuring proper alignment.
- Tap the CV axle into place using a rubber mallet or a block of wood. This may require a bit of force.
- Fasten the CV axle nut (if applicable).
9. Reinstall the Hub Assembly:
- Place the hub assembly back in place and reinstall the bolts.
10. Reinstall the Brake Caliper:
- Reinstall the brake caliper and fasten it securely.
11. Reinstall the Wheel:
- Put the wheel back on and fasten the lug nuts by hand.
12. Lower the Vehicle:
- Carefully lower the vehicle until it's back on the ground.
- Tighten the lug nuts using a star pattern to ensure even tightening.
13. Test the CV Axle:
- Start the vehicle and test the CV axle for any unusual noises or vibrations.
Remember, this is a general overview of the steps involved, and specific procedures may vary for your particular Lincoln Mark VIII model year. If you're unsure about any of these steps, it's best to consult with a qualified mechanic or refer to a specific repair manual for your vehicle.
