Part #: 200-602
New OEM Genuine Nissan rear axle outer lock nut. This nut will fit on the outer stub axle and holds the axle into the spindle. This nut will most likely need to be replaced if you are servicing the rear wheel bearings. Will fit Datsun 240Z, 260Z, 280Z, 510 and Datsun 280ZX, 1970-83. This nut is torqued onto the axle at around 200 ft lbs so it will most likely require a "cheater" bar to get loosened! This part is also known as the hub bearing lock nut.
The factory service manual recommended torque spec is 180-240 lb ft. It is difficult to achieve this torque spec so we also recommend the use of red threadlock on the nut., PT# 800-917
