Okay, so, I have had a squealing since I had a friend helping with my xj (never let a chevy tech touch my mopar again). Anyways, since then, there has been a squeal, I changed out the idler pully, but I still hear it every now and then, but it isn't persistent anymore.
I decided to change my Harmonic balancer finally. The rubber inside has been creeping its way out for some time now, and I decided it was time. My problem now is, the center bolt on the crankshaft seems seized in there. I took the belt off, tried putting it in gear and turning the bolt, but the balancer just spun. So I grabbed it with some vicegrips, which is working out for trying to loosen the bolt, but I would really be hating myself if I broke the head off of the bolt.... Figured I would wait until my xj has cooled down seeing as it is still warm, though it has been sitting for about an hour, almost 2.
Any suggestions would be appreciated, I would like to know a way to keep the motor from turning during removal and install would be great, also about the seized bolt. The jeep is a '87 pioneer xj, 4.0 straight 6
