Driveshaft angle explained
 

I've never seen it explained more clearly than this.

It t takes a $35 tool and a half hour to measure your pinion angle.

Nice vid. I know drive shafts give you problems at times but this makes it simple to understand. So much to learn...Thanks

I need to do this. I have a little vibration above 80mph...

I noticed it after I replaced a broken trans mount with a new one. The old one was broken so badly that pieces of the rubber were missing so I'm not positive what the height was before I put the new mount in. After the new mount, I noticed the vibration. I'm assuming the trans needs to be lowered slightly at the tailshaft but really need to measure the angles to be sure instead of guessing....

Great video. Really explained why phasing and opposing angles are important
