Let’s take a closer look to help you make an informed decision.
Tailshaft balancing is all about ensuring the shaft rotates smoothly without creating vibrations. Over time, wear and tear, minor damage, or changes to your vehicle’s drivetrain can throw the tailshaft off balance.
Balancing is a cost-effective and efficient option when the tailshaft is still in good condition but has developed an imbalance due to everyday use or minor damage. By rebalancing, you’re addressing the issue without the need for a full replacement, saving both time and money.
In some cases, tailshaft issues go beyond what balancing can fix. Severe damage, excessive wear, or corrosion can compromise the structural integrity of the shaft. If the tailshaft is too far gone, replacement is the safest and most reliable option.
Replacement is also ideal if you’re upgrading your vehicle for higher performance or towing capacity. A new, high-quality tailshaft can handle increased demands more effectively, ensuring your car delivers peak performance.
Ignoring tailshaft issues can lead to bigger problems down the road, affecting your car’s performance and safety. Regular maintenance and prompt attention to vibrations or unusual noises are crucial to keeping your vehicle at its best.
Deciding between balancing and replacement depends on the condition of your tailshaft and the demands of your vehicle.
For minor issues or maintenance, balancing is often sufficient and keeps your car running smoothly. However, if your tailshaft is significantly damaged or outdated, replacement ensures your vehicle remains reliable and safe.
Remember, consulting with an experienced mechanic is always a good option to guide you through these decisions.

Note: Transmission slip yokes are manufactured with various U-Joint Series. It is important to match Horsepower and Torque requirements to U-Joint Series. For aftermarket transmission applications usually a spline count and seal diameter will identify slip yoke required.
If Pinion Yoke has Placement tabs that retain the U-Joint, measure inside tabs. See Diagram D.
If Pinion Yoke does not have Placement Tabs that retain U-Joint, measure from flat of yoke inside to inside. See Diagram E.
If 4 bolt Flange is used on pinion, measure Pilot Diameter and center to center diagonally bolt hole to bolt hole. See Diagram L.
