Wood also had us measure for a new driveshaft to for our slip-yoke eliminator and sent us this beautiful clear-coated shaft. All the bad vibrations are gone now that our U-joints are happy and at less of an angle. Our driveshaft is fairly long and allows for quite a bit of downtravel without binding the double cardan. This would be different in a TJ where binding would occur with less downtravel because the driveshaft is relatively short. Also, the use of a double cardan allows you to bring the pinion up relative to the t-case. This again lessens the angles of the CV as the pinion is higher and the driveshaft is at less of a slope.
