Tools You'll Likely Need:
* Jack and jack stands: Essential for safely lifting the vehicle. Use jack stands, never rely solely on a jack.
* Wheel chocks: To secure the vehicle.
* Socket set and wrenches: Various sizes will be needed.
* Torque wrench: Extremely important for tightening bolts to the correct specification. Incorrect torque can damage components.
* Pry bar or similar leverage tool: May be needed to break free stubborn bolts.
* Penetrating oil (PB Blaster, etc.): Helps loosen rusted or seized bolts.
* New rear motor mount: Make sure you get the correct part for your specific Focus model and year.
* Repair manual: A service manual specific to your vehicle's year and model is invaluable. This will provide detailed instructions, torque specifications, and diagrams.
General Steps (Consult your repair manual for specifics!):
1. Safety First: Disconnect the negative battery terminal. Place the vehicle on a level surface, engage the parking brake, and chock the front wheels.
2. Raise and Support the Vehicle: Safely lift the rear of the vehicle using a jack and secure it on jack stands.
3. Access the Motor Mount: This often involves removing some underbody components to gain access. Your repair manual will detail what needs to be removed (exhaust components, heat shields, etc.).
4. Disconnect the Mount: This usually involves removing several bolts that secure the mount to the chassis and the transmission or engine. Penetrating oil may be necessary to loosen rusted bolts. Support the engine/transmission to prevent it from dropping unexpectedly. A transmission jack is highly recommended.
5. Remove the Old Mount: Once the bolts are removed, carefully remove the old motor mount.
6. Install the New Mount: Carefully install the new motor mount, ensuring it's properly seated.
7. Reassemble: Reinstall all the components that were removed to access the motor mount, tightening bolts to the correct torque specifications as specified in your repair manual.
8. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
9. Test: Start the engine and check for any unusual noises or vibrations. Test drive the vehicle to confirm the repair.
Important Considerations:
* Torque Specifications: Using the correct torque specifications is crucial to prevent damage. Use a torque wrench and follow the values in your repair manual.
* Support the Engine/Transmission: Always support the engine or transmission adequately to prevent damage or injury while working. A transmission jack is strongly recommended.
* Rust and Seized Bolts: Older vehicles may have rusted or seized bolts. Use penetrating oil and patience. If a bolt breaks, it will likely require more extensive repair.
* Repair Manual: This is not a substitute for a repair manual specific to your vehicle. The steps and specific procedures will vary based on your Focus's model year and engine.
Replacing a motor mount is a job best done with experience. If you're not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Improperly installed motor mounts can lead to serious damage.
