Here's a general outline of the process. Specific steps and torque specifications may vary slightly depending on your exact Bravada model. Always consult a repair manual specific to your vehicle year and model for precise instructions and diagrams. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Jack and jack stands
* Wheel chocks
* Socket wrench set (metric)
* Pry bar or pickle fork (use caution with a pickle fork to avoid damaging the boot)
* Ball joint separator (recommended, makes separation easier and safer)
* Penetrating oil (PB Blaster, etc.)
* Torque wrench
* New CV axle boot (highly recommended, even if the old one isn't visibly damaged)
* Grease for the new CV boot
Steps:
1. Safety First: Secure the vehicle safely on jack stands. Engage the parking brake. Chock the rear wheels.
2. Remove the Wheel: Remove the wheel and tire from the front driver's side.
3. Disconnect the Brake Caliper: Use a socket wrench to remove the caliper mounting bolts and carefully hang the caliper out of the way using a wire or bungee cord. Do not let the brake line hang freely; it can be damaged.
4. Disconnect the ABS Sensor (if applicable): If your Bravada has an ABS system, you'll need to disconnect the ABS sensor wire from the hub assembly.
5. Remove the cotter pin and castle nut: Locate the large nut securing the axle to the hub. Remove the cotter pin and then the nut.
6. Separate the Axle from the Hub: This is where a ball joint separator is highly recommended. A pickle fork *can* work, but risks damaging the axle. The ball joint separator will push the axle shaft out of the hub. Penetrating oil liberally applied beforehand will help.
7. Remove the inner CV joint: This is the tricky part and depends on how your Bravada's inner CV joint is secured to the transmission. Some models have a retaining clip that needs to be carefully removed (usually with a special tool). Others may require unbolting the axle from the transmission. Consult your repair manual for specific instructions. You may need to separate the transmission from the axle housing slightly.
8. Remove the CV Joint: Once the inner joint is disconnected, the entire axle shaft should be able to be pulled out.
Reinstallation: Follow these steps in reverse order. Remember to:
* Pack the new CV boot with grease.
* Torque all fasteners to the specifications in your repair manual.
* Bleed the brakes if you disconnected the brake line completely.
* Test drive carefully.
Important Notes:
* Repair manuals are crucial: This is a general overview. Specific steps and torque specifications vary by vehicle.
* Penetrating oil is your friend: Use it liberally on all bolts and connections before attempting to remove them.
* Use the right tools: Improper tools can lead to damage and injury.
* Consider professional help: If you're not comfortable with this type of repair, take your Bravada to a qualified mechanic. This job involves potentially damaging parts if not done correctly.
This is a complex repair. If you lack experience with car repair, it's best to seek professional help to avoid damage to your vehicle. Always prioritize safety.
