Here's a general outline of the process, assuming you're replacing the entire window assembly:
1. Gather Tools and Parts:
* New Window Assembly: Ensure you have the correct replacement part for your specific truck (single or double cab, specific trim level). Order from a reputable parts supplier (e.g., auto parts store, online retailer specializing in classic Ford parts). Getting the wrong part can be costly and time-consuming.
* Interior Door Panel Removal Tools: These typically include trim removal tools, screwdrivers (Phillips and flathead), and possibly a panel pry tool.
* Socket Set and Wrenches: You'll likely need various sizes to remove bolts and fasteners securing the window mechanism.
* Rivet Tool (possibly): Depending on how the window assembly is attached, rivets may need to be removed and replaced.
* Window Regulator Lubricant: Apply this to the new regulator mechanism for smoother operation.
* Safety Glasses and Gloves: Always prioritize safety.
* Shop Manual (Highly Recommended): A 1987 Ford F350 shop manual will provide detailed diagrams and instructions specific to your vehicle. This is invaluable.
2. Remove the Interior Door Panel:
* Carefully pry off any trim pieces around the window.
* Disconnect the door handle, window switch, and any other electrical connectors.
* Remove the screws and bolts holding the panel in place. Consult your shop manual for precise locations.
3. Remove the Old Window Assembly:
* Disconnect the window regulator from the window glass.
* Unbolt or unfasten the window regulator from the door. Again, the shop manual is crucial here. You might encounter rivets.
* Remove the window glass from the door. Be careful not to scratch it.
4. Install the New Window Assembly:
* Window Regulator: Install the new window regulator onto the door, securing it with bolts or rivets. Lubricate moving parts.
* Window Glass: Carefully attach the new window glass to the new regulator.
* Reassembly: Reverse the steps from removing the old assembly. Make sure everything is correctly aligned and secured.
5. Reinstall the Interior Door Panel:
* Reconnect the electrical connectors.
* Reattach the door panel.
* Test the window operation to ensure it functions correctly.
Important Considerations:
* Rust and Corrosion: On a vehicle this old, rust and corrosion are common issues that can make disassembly difficult. Penetrating oil can help loosen rusted fasteners.
* Broken Parts: You may find that other parts of the window mechanism are worn out or damaged and need replacing.
* Window Alignment: Properly aligning the window is crucial for a good seal and to prevent leaks.
* Glass Handling: Automotive glass is fragile. Handle it with care to avoid breakage.
If you're only replacing the glass: This is a simpler process, but still requires careful removal of the old glass and accurate installation of the new glass using appropriate tools and adhesives. It's highly recommended that you find a video tutorial specific to your truck model, as there are differences in the exact procedure.
Strongly recommended: Before starting, consult a repair manual specific to your 1987 Ford F350. This will provide detailed, illustrated instructions and avoid potential mistakes that could damage your truck. If you're uncomfortable with any aspect of this repair, take your truck to a qualified mechanic. This is more complex than a simple DIY project for most people.
