After paying $480, I installed the new shaft and a 4-degree shim. Regards, |Bookmarks|. The geometry you need to maintain with a double cardan drive shaft is different from that of a conventional 2 joint driveline. This increases the front u-joint angle to 12 degree. 90 and the velocity on the driving shaft were 100 F. P. S. the min. Drive shaft angle on lifted trucks. After all it really is a lot less expensive to do the job right the first time. Pros and Cons of each method: For the Toyota set-up with Old Man Emu Leaf Springs: Just by bolting the OME springs on and do nothing, the front u-joint angle would be 10. The intuitive way for most people to think of this is the fork angle on a bicycle or motorcycle. With a 3 degree joint angle, and assuming proper periodic maintenance.

When I first got my lift I thought they might be compensating for the weight of the hard top when I saw the stenciled 6" but turned out to not be the case. This type of failure can be extremely hazardous and costly especially if it occurs at a high speed. However, there is still a persistent vibration that would not go away. 4'' Lift Excessive Pinion Angle. Thanks for any input!
