Check the vehicle "posture" or "lower arm pivot height" (basically another way to measure ride height) and see if it is still within specs... that will tell you if you need to crank.
Basically you measure from the ground to the center of the lower link spindle (the center of the forward bolt that holds your lower A arm to the frame). Then you measure from the ground to the bottom of the steering stopper bracket (a little piece welded onto the A arm that the steering bottoms out against...)
Subtract the two values to get the posture measurement.
For a 4WD VG33E or VG33ER vehicle it should be between 1.791" and 1.949"
For a 2WD it should be between 1.484" and 1.642"
Oh - the VG33E is the non-supercharged 6cyl Xterra engine code. I *assume* that the VG33ER is the supercharged version.
I got these values from a Frontier manual - but they look like what I remember from the Xterra manual... 99% sure they are the same.
