shaft balancing

[RudolphOpelt]

 
"Hi everyone! I've been thinking about balancing my drive shaft on my car. I found this write-up , and it got me curious, is it really worth it?
 
It's a costly service. Maybe it's easier to just drive as is, and just change the shaft occasionally. Or is the vibration truly damaging that it's a smart investment?"
