CW is a few and far between problem, but it's always kinda cool to find out more about it. Crankwalk is sort of like having mental instability in your family. Very few get it, but every single one worries about it no matter how rare it is.
I just red a post on dsmtuners about CW with that link Matt. Sigh, now im scared to drive my car, lol, like seriously. I was told if you dont get it by 70-80k then you are safe, but man, people were saying they were getting CW at all sorts of mileage, from like 10k to 190k, and everywhere inbetween. Some people even got it as much as 3 times before finally getting a 6-bolt. I read somewhere that for 99's they changed the thrust bearing or something so it wouldnt happen, but then i hear from other sources that its BS, and the 99's have the same likelyhood to get it as any other year. I know we checked mine when we did the timing belt, and there was no play at all, but some people say that doesnt matter, and it can happen from one second to the next??


Over time the bearing will have certain amounts of play. It doesn't go from .003 all of a sudden to .007. As far as I have read, it gets subtly worse over time and you only realize it when the clutch sticks to the floor at the "very end". Honestly Ricardo, now that you have done the CW test with Jeff and me, just do it periodically and see if there is any end play. Also doing it with an actual measuring instrument is good to see exact numbers. Don't worry about it too much since FWD seem to be much less likely and you are running a stock clutch as well. Your symptoms are light at best.

Don't get paranoid about it. Like I mentioned above, very few do it, but it's like everyone expects to be the 1% that it happens to.
