Tools You'll Need:
* Jack and jack stands: Essential for safe vehicle lifting. Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheel.
* Torque wrench: Crucial for tightening bolts to the correct specification.
* Penetrating oil (PB Blaster, etc.): To loosen rusted bolts.
* Hammer: May be needed to break loose stubborn components.
* Pry bar: Might be helpful for separating components.
* Sockets and wrenches (metric): A complete set will be necessary. You'll likely need sizes ranging from 10mm to 19mm, potentially larger.
* Axle nut socket (typically a large 36mm or similar): This is a special socket needed for removing the axle nut. Often these are impact sockets.
* Impact wrench (highly recommended): Makes removing the axle nut significantly easier. If you don't have one, expect a tough time with a breaker bar.
* CV joint boot clamps: New ones are necessary if you're replacing the entire axle assembly.
* New passenger-side axle assembly: Get the correct part for your specific vehicle.
* Gloves and safety glasses: Protect yourself from grease and debris.
* Shop rags: For cleaning.
* Drain pan: To catch any fluid that might spill.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Raise the vehicle securely using the jack and support it with jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the passenger-side front wheel.
3. Disconnect the Brake Caliper: Remove the brake caliper mounting bolts and carefully hang the caliper out of the way using a wire or bungee cord. Don't let the brake line hang freely.
4. Disconnect the ABS Sensor (if equipped): Carefully disconnect the ABS sensor wire from the axle housing.
5. Remove the Axle Nut: Use your impact wrench or a breaker bar and a large socket to remove the large axle nut. This is often very tight. Use penetrating oil beforehand.
6. Separate the Axle from the Transaxle/Differential: This is often the trickiest part. You may need to gently tap the axle housing with a hammer and pry bar to separate it from the transaxle. The axle usually slides out from the differential.
7. Remove the Axle from the Hub: The inner CV joint will separate from the hub assembly. Some gentle persuasion (tapping) may be required.
8. Install the New Axle: Reverse the removal process. Ensure the new CV joint is correctly seated into the transaxle/differential and the hub.
9. Install the Axle Nut: Tighten the axle nut to the manufacturer's specified torque (consult your repair manual).
10. Reconnect Components: Re-attach the brake caliper, ABS sensor (if equipped), and wheel. Install new CV joint boot clamps if necessary.
11. Lower the Vehicle: Carefully lower the vehicle.
12. Torque Wheel Bolts: Tighten the wheel lug nuts to the manufacturer's specified torque.
Important Considerations:
* CV Joint Boots: If the CV joint boots are torn or damaged, they MUST be replaced. A torn boot will allow grease to escape and dirt to enter, leading to premature axle failure. This often necessitates replacing the entire axle assembly.
* Wheel Bearing: Inspect the wheel bearing while the axle is out. If it's noisy or feels loose, it may need to be replaced as well.
* Repair Manual: A repair manual specific to your 1993 Subaru Loyale is highly recommended. It will provide detailed instructions, torque specifications, and diagrams.
