2001 was the only year they said 159 even though the bearing is exactly the same and nothing changed at all on the car.
Then in 2002 it was right back to 118 ft lbs. Its always going to be 118, no matter the year of the grand prix (97-08).
Awesome, thats good to know. My axle nut is 36mm (which I found out I don't have) so I was going to do it yesterday after work but now I need to go get the socket after work. I will report my success or failure later tonight.
