Installation Guide
Installation of automotive drivetrain components requires mechanical expertise and specialized tools. It is highly recommended that installation be performed by a qualified automotive technician.
General Installation Steps (Consult Service Manual for Specific Vehicle):
- Safety First: Ensure the vehicle is securely lifted and supported on jack stands. Disconnect the battery. Wear appropriate personal protective equipment (PPE).
- Vehicle Preparation: Mark the driveshaft and differential flange for proper reassembly alignment. Drain transmission fluid if necessary, or be prepared for fluid loss from the tailshaft.
- Remove Old Component: Disconnect the U-joints from the differential flange. Carefully slide the driveshaft assembly, including the old slip yoke, out of the transmission tailshaft.
- Inspect Components: Thoroughly inspect the transmission output shaft seal for wear or damage. Replace if necessary. Inspect the U-joints for wear and replace if needed.
- Install New Slip Yoke: Apply a thin layer of transmission fluid or appropriate lubricant to the splines of the new ACP FM-EY002 slip yoke. Carefully slide the new slip yoke onto the transmission output shaft, ensuring proper spline engagement.
- Reassemble Driveshaft: Connect the driveshaft to the new slip yoke using the appropriate U-joints and retaining clips. Align the driveshaft with the marks made on the differential flange and secure it.
- Fluid Check: Check and refill transmission fluid to the correct level as per vehicle manufacturer specifications.
- Final Checks: Verify all fasteners are tightened to specifications. Ensure there is no binding or excessive play in the drivetrain components.
Note: This slip yoke is designed for 1960-1976 Fairlane, Falcon, Mustang, and Torino models with 28-spline transmissions and 1 1/16" U-joint caps, typically found with small block V8 engines. Verify compatibility with your specific vehicle before installation.
Functionality
The slip yoke's primary function is to connect the transmission output shaft to the driveshaft. It allows for changes in driveshaft length as the vehicle's suspension moves up and down, preventing stress on the transmission and differential. The slip yoke transmits rotational power from the transmission to the driveshaft, which then transfers it to the differential, ultimately driving the wheels.
Maintenance and Care
The ACP FM-EY002 Drive Shaft Slip Yoke is a durable component, but regular inspection is crucial for optimal performance and longevity of your vehicle's drivetrain.
- Regular Inspection: Periodically inspect the slip yoke, U-joints, and the transmission tailshaft seal for any signs of wear, corrosion, leaks, or damage.
- Lubrication: Ensure proper lubrication of the U-joints as per your vehicle manufacturer's specifications. While the slip yoke itself is lubricated by transmission fluid, the U-joints require separate attention.
- Cleanliness: Keep the area around the slip yoke free from excessive dirt and debris, which can accelerate wear on seals and moving parts.
Troubleshooting
If you experience any of the following symptoms, it may indicate an issue with the slip yoke or related drivetrain components:
- Vibration: A common symptom of a worn or improperly installed slip yoke or U-joint. Vibrations may be felt at certain speeds or under acceleration.
- Clunking Noise: A noticeable clunking sound, especially when shifting gears, accelerating from a stop, or changing direction, can indicate excessive play in the slip yoke or worn U-joints.
- Fluid Leaks: Leaks from the transmission tailshaft area may suggest a damaged transmission output shaft seal, which can be exacerbated by a worn or improperly seated slip yoke.
If you encounter any of these issues, it is recommended to have your vehicle inspected by a qualified automotive mechanic for proper diagnosis and repair.
