DeeAone- there was a recall to fix the keyway at one point IIRC"See that car, in the 80's that car was deadly." Random man to his son while passing the GTX in a parking lot

The crank pulley wobble is not only caused by a possible worn keyway/cranknose issue.
the other reason is the drive pulley on the crank that drives the alt/PS/AC pump belts has a vulcanized rubber sandwich piece between 2 metal pulley pieces. This rubber fails over time and allows the pulley to wobble.
Its not always the crank keyway.
Even my BPT pulley wobbles a bit, and I know its not the cranknose or keyway.

PS: Yes there was a TSB for the crank issue. I know of one GTX in 1995 that got a new crankshaft installed under the TSB after the nose snapped off. That was keith Armbrusters GTX at the time.

I remember reading a post on the yahoo forum regarding the crank keyway issue. The person (was it John Jackson?) stated that the keyway failure was most likely due to the design and placement of the pulleys, and the stress it caused to the crank pulley. He said that it was best to keep the belts (AC, PS, Alt) as loose as possible, w/o them squealing, to keep the load minimized.
Or something to that effect.

I don't have AC but after reading that I went out and loosened all my drive belts!

Must have made a good mess in the timing belt area.
Good thing the engine is a non interference unit, or else all sorts of engine damage could happen.
