Tools You'll Likely Need:
* Jack and jack stands: To safely lift and support the vehicle.
* Wheel chocks: For added safety.
* Sockets and wrenches: Various sizes, including a socket that fits the driveshaft nut (likely a large one).
* Hammer: For separating components (use carefully).
* Penetrating oil (like PB Blaster): To loosen rusted or seized fasteners.
* Pry bar (optional): May be helpful for separating components.
* Torque wrench: For proper reassembly.
* Gloves: Protect your hands.
* Safety glasses: Protect your eyes.
General Steps (Consult your repair manual for specifics):
1. Safety First: Securely lift the vehicle using a jack and place it on jack stands. Engage the parking brake and use wheel chocks.
2. Locate the Driveshaft: Identify the driveshaft you need to disconnect (front or rear; most likely the front).
3. Remove the Wheel: Remove the wheel on the side of the driveshaft you're working on to gain better access.
4. Disconnect the Driveshaft from the Differential or Transaxle: This is typically done by removing the large nut securing the driveshaft to the differential or transaxle flange. Spray penetrating oil onto the nut beforehand to help loosen it. You may need to hold the driveshaft flange with a wrench or socket while removing the nut. Once the nut is removed, the driveshaft should separate from the differential/transaxle. Sometimes, a little persuasion with a hammer and pry bar might be needed to separate the parts, but use caution to avoid damage.
5. Disconnect the Driveshaft from the Transmission (if applicable): Depending on your model and if it's a front-wheel-drive or rear-wheel-drive car (most likely front-wheel-drive for a 626), there may be another connection to the transmission that needs to be disconnected. This could involve removing bolts or clamps.
6. Remove the Driveshaft (if necessary): Once disconnected at both ends, you may need to carefully remove the driveshaft from the vehicle.
Important Considerations:
* Different Models: Mazda 626s varied slightly over the years. Your specific model may have different components or procedures. Refer to a repair manual for your exact year and model.
* CV Joints: Be careful not to damage the CV joints (constant velocity joints) during the process. They are crucial for smooth operation.
* Reassembly: Remember the order of assembly and torque specifications when putting everything back together. Improper reassembly can lead to vibration, damage, or even failure.
* Professional Help: If you're not comfortable with car repair, consider seeking professional help from a qualified mechanic. Improperly disconnecting or reconnecting driveshafts can lead to serious issues.
Again, this is a generalized overview. A repair manual specific to your 1989 Mazda 626 is absolutely essential for safe and correct completion of this task. Failure to follow proper procedures could result in injury or damage to your vehicle.
