Here's a general outline. Always consult a repair manual specific to your vehicle year and model for precise details and torque specifications. This is not a substitute for a proper repair manual.
Tools You'll Likely Need:
* Jack and Jack Stands: Absolutely essential for safety.
* Wheel Chocks: To secure the vehicle.
* Torque Wrench: Crucial for proper tightening of bolts.
* Socket Set and Wrenches: Various sizes, likely including metric.
* Ratchet and Extensions: To reach difficult bolts.
* Pry Bar or Similar: May be needed to separate the mount from the transmission.
* New Transmission Mount: Make sure you get the correct part for your 2003 Focus ZTS 2.3L.
* Penetrating Oil (PB Blaster, etc.): Highly recommended to loosen any rusted or seized bolts.
* Gloves and Safety Glasses: Protect yourself.
Procedure (General Steps - Consult your repair manual for specifics):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Raise the vehicle securely using a jack and support it with jack stands. Never work under a vehicle supported only by a jack.
2. Access: You'll likely need to partially lower the front of the transmission to access the mount. This often involves disconnecting some components. Your repair manual will show what needs disconnecting (potentially exhaust components, possibly motor mounts, etc.) This step varies considerably from general descriptions. Careful observation and photographic documentation of disassembly are crucial.
3. Disconnect the Old Mount: Locate the transmission mount bolts. Apply penetrating oil liberally and allow it to soak. Use the appropriate sockets and wrenches to carefully remove the bolts. You may need a pry bar to gently separate the mount from the transmission and the chassis.
4. Install the New Mount: Carefully align the new transmission mount and install it in the reverse order of removal. Ensure it's properly seated before tightening the bolts.
5. Reconnect Everything: Carefully reconnect all the components you disconnected earlier.
6. Lower the Vehicle: Slowly lower the vehicle using the jack.
7. Torque Specification: Use your torque wrench to tighten all bolts to the manufacturer's specifications (found in your repair manual). This is critical to prevent future problems.
8. Test Drive: Carefully test drive the vehicle to ensure the new mount has solved the problem. Check for vibrations or unusual noises.
Important Considerations:
* Accessibility: This job is physically demanding due to limited access under the vehicle.
* Bolts: These bolts can be incredibly stubborn due to rust and corrosion. Be prepared for a struggle and potentially broken bolts. If a bolt breaks, you may need to drill it out and use a helicoil or time-sert to repair the threads.
* Repair Manual: Investing in a repair manual specific to your vehicle is highly recommended. It will provide detailed diagrams, torque specifications, and procedural steps. Improper repair can lead to damage to your vehicle.
If you're not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. This is not a beginner's job, and improper repair can cause significant damage.
