It's a common issue. Eventually the car will start stalling on you and then, like mine did, will leave you stranded. It's not that difficult to change but it would help if you had access to a lift like I had. You'll need balancer puller, I just went to Advance and got one, and you'll need the 1/4x28x3 bolts that did not come with the puller. Make sure that you get the bolts aligned correctly, it's kind of tricky, and also the center puller blot where it goes into the crank, I used a socket to keep it from messing up the threads for the balancer bolt. Once the balancer is off you can take it from there. Good luck.
