Methods:
* Using a short socket and ratchet: This is the most straightforward approach *if you have enough clearance*. You'll need a very short socket (likely a 13mm or 15mm – check your manual) and a ratchet with a short extension, ideally a swivel extension for added maneuverability. Try different angles and positions to find the best approach. Often, a shallow-well socket is necessary because of the limited space.
* Using a wrench: A short, open-ended wrench or a combination wrench might offer better access than a ratchet in tight spaces. Again, maneuverability is key.
* Using a wobble extension: This extension allows for more flexibility in the angle of your ratchet, significantly increasing your chances of getting a good grip on the bolt.
* Removing other components for better access: This is often necessary. Depending on the specific engine and your comfort level, you might consider removing:
* The exhaust manifold heat shield: This is often directly in the way.
* Part of the exhaust system: More time-consuming but may give you the best access. This *requires* properly supporting the exhaust system to avoid damage and potential injury.
* The starter motor's wiring harness: This might provide a little more room, but usually isn't necessary unless you are having trouble with the other methods.
* Using air tools: An impact wrench can sometimes break loose stubborn bolts, but be careful not to strip the bolt head. The small space can make it difficult to control the impact wrench, potentially causing damage.
Important Considerations:
* Safety First: Disconnect the negative battery cable before starting any work on the starter. This prevents accidental shorts and protects you from injury.
* Proper Tool Usage: Use the right size socket or wrench to avoid stripping the bolt head.
* Patience: This is a challenging job. Don't force anything. Take your time and try different angles and approaches.
* Consult a Repair Manual: A Haynes or Chilton repair manual for your specific year and model Expedition will provide detailed diagrams and instructions. This is highly recommended.
* Professional Help: If you're uncomfortable working on your vehicle or are having trouble removing the bolt, consider taking it to a qualified mechanic. The cost of professional repair may be less than the cost of damaging your vehicle.
Remember to always use caution when working under your vehicle and ensure it's properly supported. If you're not comfortable doing this yourself, a professional mechanic is the safest bet.
