your problem may also because of the timing belt so check that whether it is in good condition . i think replacing the timimg gear will help you

CCW , and your going to at least put the new timing belt on and balance to check for compression. you can run an engine without the covers installed or accessories hooked up

SOURCE: Driveshaft yoke balancer
I had the same problem and removed the balancer from the drive shaft this morning. I put the drive shaft back on, and drove the truck around all day, highway, city, stop and go, there were no problems, and the noise was gone, and I had no vibrations at all. So you should be fine if you remove the balancer.

Hello, I dont mean to be the bearer of bad news but I have had three of these cars to do the same exact thing. The harmonic balance loosened up and it wore the end of the crankshaft and the balancer would not tighten up any more. The best option is to replace the crankshaft and balancer. There is not a quick fix fix this. Sorry. Please rate my answer. Thank you.
