Just looking at my harmonic balancer over the weekend...it's never been replaced, and it's the original (faulty) part number.

It looks like I'll need a large hex socket to loosen the bolt holding the balancer on. It's a large hex bolt, similar (but larger) than the one used to open the diff drain holes. Here's a picture of the socket type I'll need:

Does anyone know the size I need to remove the harmonic balancer? They are about $20 each, so I don't want to guess the wrong size.

You will need a 17mm hex bit and some means to hold the harmonic balancer from turning.
