bent driveshaft question

lost the front u joint on the rear DS going about 50mph two days ago. It hit the underside so hard it put a small hole and a large dent under the pass seat. Didn't have a vice big enough to press in the new joints after removing the old ones. Took it to a shop and had them press them in for me. They told me the shaft is visibly bent and to have it rebalanced.

Has anyone successful had one rebalanced before? Is it junk now or is it salvageable?

thanks

if you get a vibration then a rebalance will work if the shaft integrity is still good.

If you drive it on the road and the shaft is bent, it's most likely trashed. It's not worth making it straight again because it's almost the same as making a whole new shaft. Beings as you drive it on the road, I would have one made and balanced. Mine is visibly a banana, but it never sees the road.

I worked in a driveshaft shop when I was in college and we used to straighten bent shafts daily. We did everything from passenger vehicles, to OTR trucks, to off-road only dump trucks and loaders. To say that it would be as much work as having a new one built without seeing it is foolish. Driveshaft tubing isn't cheap.

Let the driveshaft shop decide what would work. It's amazing what you can do with an oxy-acetylene torch and a blast of air from a compressor to straighten out a bent tube. We would get ours so straight (within 0.003" of runout) that balancing was not necessary.
