1. imbalanced Driveshaft: If the new driveshaft is not correctly balanced, it can cause vibrations that lead to juggling. Balancing involves ensuring the driveshaft's weight is distributed evenly. An unbalanced driveshaft can put stress on the car's components, leading to further issues.
2. Incorrect Length: If the replacement drive shaft is not the correct length, it can cause misalignments and vibrations. Too short or long driveshaft can affect the power transmission and cause juggling.
3. Damaged U-Joints or CV Joints: If the driveshaft's universal joints (U-joints) or constant velocity joints (CV joints) are worn or damaged, they can cause vibrations and juggling. These joints allow for movement and power transmission between the driveshaft and other components.
4. Faulty Installation: Improper installation of the drive shaft can also contribute to juggling. Incorrectly secured or misaligned bolts, nuts, or components can cause vibrations and abnormal movement.
5. Mounting issues: If the driveshaft is not mounted properly, it can cause the entire assembly to vibrate. This can happen if the bolts that hold the driveshaft in place are too tight or too loose, or if the driveshaft is not properly aligned.
6. Driveline Angle Issues: The driveshaft must be installed at the proper angle to prevent vibrations. If the angle is incorrect, it can cause the driveshaft to bind and cause juggling.
7. Damaged Transmission or Differential: In some cases, a juggling after changing the drive shaft could indicate underlying issues with the transmission or differential. Worn gears or damaged components within these systems can cause vibrations that travel through the driveshaft.
To address this issue, it's recommended to consult with a qualified mechanic or visit a reputable auto repair facility. They can properly inspect the driveshaft and related components, identify the root cause of the juggling, and perform the necessary repairs or adjustments.
