You jack the back wheels off the ground, start it, put it in gear, and Rev it up until you feel the vibration. Then while it's at that rpm, take a marker taped to a stick and slowly raise the marker until it barely ticks the driveline. Do it at both ends and the middle.
I did this.
Down near the pinion, I got a nice straight line all the way around.
Up by the transmission I only got about a 2" long mark. About 1/4 of the whole circumference of the driveline.
The mark denotes the heavy side.
So I mounted two hose clamps on the opposite side of the mark.
Took it for a spin. Drove it around varying my speed.
A definite change for the better. So much so, I'm not sure if there's still an itsy bitsy vibration, or it just the rough roads.
I still plan on taking it to a shop to have it balanced, I just wanted to personally tag down that it was the driveline.
Next I'll move on to installing a front sway bar.
Then perhaps power drum brakes. Discs are still a ways down my 'To Do' list.
Thanks everyone for the help.
