has anyone encounter a problem with the harmonic balancer separating for these vehicles. I have replaced it three times and they keep separating. This may happen on other vehicles as well. Can it be too much tension on the balancer?>
If you are using recycled harmonic balancers, at the recycle yard, they may be pulling the harmonic balancer by the its outside metal part. This method will overstress the rubber between the inner and outer metal parts. It will soon fail. You may have to go new.
