WARNING: This page is about a different car, the 2005 Nissan Xterra. However, it is still accessible from the selected car via links, so may be relevant.

Measure the deflection of flywheel contact surface to clutch with a dial indicator.
Measure the deflection at 210 mm (8.27 in) dia.
Standard: 0.45 mm (0.0177 in) or less .
If measured value is out of the standard, replace flywheel.
CAUTION: When measuring, keep magnetic fields (such as dial indicator stand) away from signal plate of the rear end of crankshaft.
