Laser Arm Description One of the common problems with all PS2 Console models is the PS2 Laser Arm loses it&39s elasticity & causes them to buzz grinding noise & in extreme cases the disk won&39t load at all. Replacing the plastic PS2 laser arm & re-greasing the worm drive on the plastic PS2 laser arm can in some cases resurrect a previously non-working machine. Note: These are brand new original Sony parts. Usually ships within 24 hrs.
