An FYI, the year 2001 is the only year that is 159 ft lbs.

Why? Because GM is stupid.

Then in 2002 boom, its back to 118.

Hell even a 2009 Chevy Impala with a 3.9 v6, with the same control arms and trans and wb's and axles its 118 ft lbs.

A 2000 GTP is the same as a 2001 GTP so the Torque spec of 118 is still going to be what it is.
