1. Preparation:
* Consult a repair manual: A Chilton's or Haynes manual specific to your 1996 Ford Festiva is highly recommended. It will show you exactly where the cable connects at both the transmission and the instrument cluster. This is crucial to avoid damaging anything.
* Gather supplies: You'll need a suitable lubricant (more on that below), rags, and possibly some small tools like screwdrivers (possibly a small torx or security bit depending on the fastener type), pliers (potentially needle nose), and perhaps a small wire brush to clean the cable ends.
2. Disconnecting the Cable:
* Transmission end: Locate the speedometer cable where it connects to the transmission. This usually involves removing a retaining clip or nut. The manual will show you the exact method. Be prepared for it to be somewhat difficult to access depending on the space around your transmission.
* Instrument cluster end: At the instrument cluster, find where the cable connects. Again, your repair manual is your best guide here. You'll likely need to remove the instrument cluster bezel (the plastic trim around the gauges) to access it properly. This typically involves some unscrewing.
3. Lubrication:
* Cable type: Speedometer cables are usually either flexible or have a solid inner wire within a flexible sheath.
* Lubricant: Do NOT use WD-40. It's a solvent and will evaporate, leaving the cable drier than before. Use a specialized cable lubricant designed for speedometer cables, or a light weight grease such as lithium grease. A very small amount is all that's needed.
* Application: With the cable disconnected, apply a small amount of lubricant to the cable end at the transmission. Gently work the lubricant in, moving the cable back and forth slightly. You might need to use a small brush or something similar to help distribute the lubricant into the cable. Avoid excessive grease.
* Testing: Once you've lubricated the transmission end, you may want to test the cable before putting it back together. Gently rotate the cable to feel if it turns smoothly and easily.
* Instrument Cluster End: If possible, repeat the lubrication process at the instrument cluster end if you can access it easily.
4. Reassembly:
* Carefully reconnect the cable to the transmission and instrument cluster, ensuring it's properly seated.
* Reassemble the instrument cluster bezel.
5. Testing:
* Start the car and check if the speedometer is working correctly.
Important Considerations:
* Patience: This is a delicate job. Take your time and don't force anything.
* Safety: Disconnect the negative battery terminal before working on the electrical components, particularly the instrument cluster.
* Cleanliness: Use clean rags to avoid contaminating the cable with dirt or debris.
If you're uncomfortable with this task, it's best to take your Festiva to a mechanic. A poorly lubricated or incorrectly reassembled cable can lead to inaccurate speedometer readings or even cable damage.
