The shop that looked at it to see if it needed a front end alignment took off the driveshaft and ran without it connected. They said the shaft was too short. I looked at the front yoke and appeared that it could be 1.75" longer. Which may be causing the whip/vibration. The vibration happens after about 30-3mph all the time. Seems the cab shakes not the steering wheel.

If the motor and rear are correct year and the tranny was the only variable, how could the driveline angles be off? If so, how would I know and how would I correct?
