Tools You'll Likely Need:
* Jack and jack stands: Absolutely essential for safety.
* Wheel chocks: To prevent the car from rolling.
* Lug wrench: To remove the wheel.
* Ball joint separator: To separate the ball joint from the control arm (some methods avoid this).
* Hammer and punch (or pry bar): For various separating tasks.
* Socket set and wrenches: Various sizes, including metric.
* CV axle puller: Makes removing the axle much easier. A slide hammer is often used in conjunction with this.
* Penetrating oil (PB Blaster, etc.): To loosen rusted or seized components.
* Torque wrench: Crucial for tightening bolts to the correct specifications.
* New CV axle: Get a quality replacement part.
* Grease: For repacking the CV joint (optional but recommended).
* Safety glasses and gloves: Protect yourself.
Steps (General Outline – Consult Repair Manual for Specifics):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Jack up the car and securely support it on jack stands. Remove the wheel.
2. Disconnect the Axle:
* Inner Joint: This is often the trickiest part. You may need to disconnect the inner joint from the transmission. This often involves removing a retaining clip and possibly some bolts. The method varies depending on the transmission type. Consult your repair manual for the correct procedure.
* Outer Joint: This typically involves separating the ball joint from the control arm (some methods avoid this step, see note below). Use a ball joint separator to carefully separate the ball joint. Then, remove the cotter pin and castle nut from the axle.
3. Remove the Axle: Now that the axle is disconnected at both ends, use a CV axle puller to remove the axle from the hub. If you don't have a puller, it can be extremely difficult to remove.
4. Install the New Axle:
* Installation is generally the reverse of removal. Carefully install the new axle, ensuring the splines are properly engaged. You may need to lightly tap the axle into place.
* Outer Joint: Re-attach the outer joint to the steering knuckle, ensuring it's properly seated. Tighten the castle nut to the correct torque specification. Install the cotter pin.
* Inner Joint: Connect the inner joint to the transmission. Again, your repair manual is critical for the proper procedure here.
5. Reassembly: Reassemble everything in the reverse order of disassembly. Torque all bolts to the manufacturer's specifications.
6. Test Drive: After reassembly, test drive the car carefully to check for any vibrations or unusual noises.
Important Note: Some methods for replacing CV axles on this vehicle avoid separating the ball joint. This often involves carefully maneuvering the axle out of the hub while keeping the ball joint attached. This can be challenging and requires careful attention to avoid damage. Your repair manual will detail the best approach.
