* Hard to close? This might be due to misalignment or binding.
* Sagging? This points to worn hinges or loose mounting bolts.
* Not latching properly? This could involve striker plate alignment or latch mechanism issues.
* Making noise? Loose hinges, worn bushings, or other loose parts are likely culprits.
Before you start, safety first! Use jack stands to support the vehicle securely if you're working underneath. Always disconnect the negative battery terminal to prevent accidental short circuits.
Here's a breakdown of common adjustments:
1. Hinge Adjustment:
* Locate the hinges: The hinges are located on the door and the body. You'll likely find both have adjustment points.
* Types of adjustment: Most hinges will have either:
* Bolts with slots: These allow for vertical and horizontal adjustment. Loosen the bolts, adjust the door's position, and tighten the bolts. Small adjustments are key—over-tightening can strip the bolts.
* Eccentric bushings (cam bolts): These cylindrical bolts have an off-center hole. Rotating them changes the door's position. A wrench or socket may be needed.
* Adjustment process: Carefully loosen the hinge bolts. Make small adjustments to the door's position, checking frequently for improvement. Tighten the bolts once you've achieved the desired alignment. Repeat for all hinges.
2. Striker Plate Adjustment:
* Locate the striker plate: This is the metal plate on the doorjamb that the door latch engages with.
* Adjustment: The striker plate often has slots for adjustment. Loosen the screws and move the plate to improve latch engagement. You might need to adjust it up/down or left/right.
* Test the latch: Check the door latching after each minor adjustment.
3. Door Latch Mechanism:
* Complexity: Adjusting the latch mechanism is more involved and may require specialized tools or knowledge. If you're not comfortable with this, it's best to consult a mechanic.
Important Considerations:
* Check for worn parts: Before adjusting, inspect the hinges for wear or damage. Worn bushings or damaged hinges will require replacement.
* Grease hinges: Lubricate the hinges with a suitable lubricant to reduce friction and noise.
* Consult a repair manual: A repair manual specific to your 2004 Ford Focus will provide detailed diagrams and instructions.
* Professional help: If you're uncomfortable performing these adjustments, it's always best to seek help from a qualified mechanic. Improper adjustments can worsen the problem or damage the vehicle.
Remember to test the door repeatedly during the adjustment process. Small adjustments are better than large ones to avoid damaging the door or its hinges. If the problem persists after trying these adjustments, a more significant issue may be present requiring professional attention.
