Tools you'll likely need:
* Screwdrivers: Phillips and flathead, various sizes.
* Sockets and wrenches: Metric sizes, likely 8mm, 10mm, and possibly larger.
* Pliers: Needle-nose and regular.
* Panel removal tools: To avoid scratching the interior trim.
* Interior door panel removal instructions: These are readily available online via YouTube videos or repair manuals. Often involves removing screws, carefully prying clips, and disconnecting electrical connectors.
* Replacement parts: Ensure you have the correct latch assembly and linkage rods for your specific door.
General Procedure (Adapt based on your repair manual):
1. Door Panel Removal: Carefully remove the interior door panel. This usually involves removing screws around the armrest, door handle, and possibly the window crank. There are often plastic clips holding the panel in place; use panel removal tools to avoid breaking them. Disconnect any electrical connectors (power window, door lock).
2. Latch Mechanism Access: With the panel removed, you'll have access to the door latch mechanism. You may need to remove some additional screws or clips to access the latch assembly and rods fully.
3. Rod Disconnection: Carefully disconnect the linkage rods from the latch mechanism and the door handle. Take note of how they're connected—draw a diagram or take photos if necessary. Some rods may be held in place with clips or small screws.
4. Latch Assembly Removal: Carefully remove the old latch assembly. This might involve removing screws or bolts securing it to the door. Pay attention to how it's positioned; this is crucial for reinstallation.
5. Installation of New Parts:
* Latch Assembly: Carefully install the new latch assembly, ensuring it's properly aligned and secured with the appropriate fasteners.
* Rods: Connect the linkage rods to the new latch mechanism and door handle, matching your previous notes or photos. Make sure the rods are correctly seated and the connections are secure.
6. Reassembly: Carefully re-attach the door panel, ensuring all clips and screws are properly installed. Reconnect any electrical connectors.
7. Testing: Test the door lock and unlock mechanisms to ensure everything is working correctly.
Important Considerations:
* Repair Manual: A repair manual specific to your 1998 Chevy Cheyenne is invaluable. It provides detailed diagrams and instructions that are far more accurate than a general guide.
* Safety: Disconnect the negative battery terminal before starting any electrical work.
* Patience: Take your time and be methodical. Rushing can lead to mistakes and damage.
* Professional Help: If you're uncomfortable performing this repair yourself, consider taking your vehicle to a qualified mechanic.
This is a general overview. The exact steps will vary depending on the specific problem and your truck's configuration. Again, consult a repair manual for precise and accurate instructions.
