When I first bought my truck the balancer was wobbly. At speeds over 45 mph, I had some engine vibration. I sent it to Damper Dudes to be rebuilt. After the repair the vibration was gone. Based on that, I would never use a damaged balancer..
Including the shipping it was right around a hundred bucks.
Remember the recent post from Jerry in Salt Lake City. His balancer flew apart on the road and fatally injured his radiator. The hundred bucks is cheap compared to a radiator re-core and possible engine damage due to excess vibration.
