The first one was replaced because the center was cracked and made less tension on the belt which caused the battery to die. It worked for about a month, Then the second one started wobbling like it was a defect and now the third one is doing the same like something is bent. Hope this helps on giving me advice on how to fix

That's pretty much unheard of. I would question whether something is wrong with the crankshaft leaving the Balancer loose on the shaft but there is no reason for a tight balancer to fail like that. The only way they fail is if the rubber attaching the 2 parts rots away and that's not happening on a brand new balancer.
