Hi all!
 
I'm experiencing vibrations from my driveshaft at high speeds, and it's becoming a real headache. Has anyone had this problem before? 
 
I'm now figuring out the best solution:
 
Remove the driveshaft and use a balancing machine. It's a reliable method, though it's a bit of a hassle and expensive. I've also heard it can be balanced right on the car. They do it on a lift without removing the shaft using some equipment.
 
Has anyone  balanced their driveshaft  this way? Please share your experiences and results. Thanks in advance!
