IFS front driveshaft alignment #764680 11/12/06 01:51 AM

Getting the Wheeling Fever
The two rear mounts that hold the rigid IFS axle to the frame have holes that are quite a bit bigger than the bolts. Is that to allow room to shift the angle of the axle to align the u-joints properly? Ever since I switched out my front end diff and bolted things back in, I have had a much harsher vibration with the front shaft turning than before.

You would want to set the angle on the u-joint to be at 90 degrees to the driveshaft top-bottom and side-side:
