Hose Clamps to Balance Drive Shaft

[Blown]

Just crazy to me to see this work. I heard of it and finally tried it. It's similar to balancing tires with beads/BB's or Centramatic wheel balancers. I also found drive shaft balancers made similar to the Centramatics.

I placed two identicle hose claps on the driveshaft end, in the same direction and with the screwdowns at 180 degrees to each other. If it's balanced the clamps should stay how you put them. The clamps have to be tightened enough to stay in position when you stop but must be able to freely rotate around the driveshaft. Then you take a drive. They moved into the position you see in the pic. I placed them back at 180 degrees apart. I took another drive, they moved back to these positions, the vibe stopped again, so I tightened them down. I did the same at the same time at the front of the shaft at the differential and they did not move so I think the front is in balance and removed them.

I checked the balance on the rear driveshaft using this method too. It was off a bit. I had to get the rear shaft retubed (too short duh) and it was right on when I checked it using this method. I had also told the driveshaft shop and think they did a better job the second time around on the balancing.

There are many other factors that could be leading to driveshaft vibes, but this help me solve one.
