Yeah - the pulley bolt is a pain - best use a good air-impact for it. My 600 ft-lb Ingersoll-Rand barely took it off - it was strugguling to loosen it for a couple seconds. Consider that your lug nuts are usually under 100 ft-lb... I did this with an engine that was out of the car, so access wasn't an issue either. Before I had an air-compressor and air tools, I would drive down the street to a shop to have them loosen bolts like that.

v8i I'm going to take it apart very soon... I'll prob post more asking questions while the repair is in progress, thanks guys!

 

So my car is a v8i 4.0 would the key cause the same issue on that motor... I dropped it off at a mechanic and he told me the wobble isn't enough to be an issue and most of the discos he has seen have a little wobble to the crank pulley... ???
