FRONT DRIVESHAFT RECLOCKING INSTRUCTIONS
Driveshaft modification will need to be performed if the vehicle experiences a driveshaft vibration . The reason for this
vibration is that the factory driveshaft u-joints are not aligned from the factory. The next steps will allow the yoke to be
turned on the driveshaft, thus eliminating the factory vibration. Normally this vibration is only felt when the vehicle is in
4wd at speeds in excess of 40mph.
1. Mark the driveshaft as shown in Photo 1. and Unclamp the boot on the driveshaft as shown in Photo 2.
2. Remove the stock clamps and driveshaft boot and separate the driveshaft. Locate the tab on the driveshaft splines
to be ground. See Photo 3.
3. Groove the shaft as shown with die grinder as shown in Photo 4.
4. The finished groove is shown and will be the same as the rest of the grooves.
5. Reinstall the driveshaft yoke 90 degrees from where it was factory. This will align the u-joints. Make sure the u-joints
are aligned before assembling the shaft.
6. Re-clamp the boot on the driveshaft with the factory clamps and using a clamping tool.
