Rebuilt t-case with slip yoke Oliver's CV driveshaft. Still having vibrations seems to be in the rear. I can press in clutch coasting down the highway and it goes away then come back after I release it. Any suggestions?
With a double cardan style rear driveshaft, the pinion yoke should be pointing directly at, if not maybe 1-2 degrees below the transfer case rear output.
If you have a link suspension in the rear you can point it directly at the rear output. If you have leaf springs that allow more axle wrap, you may need to point it a few degrees lower than the output shaft and allow the position of the pinion to be in line with the output shaft when under throttle. But excessive wrap makes getting the correct angle a challenge without having decel vibes.
Make sense?
