Did you ever watch an in car video of a race and notice how little the driver has to turn the wheel when he goes through the turns? Did you ever wonder why you have to crank your steering wheel 360 degrees to get the same turn? The answer lies in the ratio of the steering rack, which translates the motion of the steering wheel into lateral forces that push the front wheels from side to side, allowing you to turn the car. The Nissan 300ZX uses a rack and pinion steering rack. The wheel turns an input shaft which spins a gear within the rack.

That gear pushes on a rod within the rack, moving it from side to side. The tie rods on either end allow the wheel to move through its suspension range and still receive inputs from the driver.

The Nissan 300ZX’s steering rack is an absolutely critical piece of equipment. If should be examined periodically to be certain that it is not leaking. You can squeeze the boots of the rack to feel if there is still internal lubrication. If the boots are torn or otherwise damaged, it is likely that the grease has already leaked out, which compromises the rack. If your Nissan 300ZX’s steering rack fails, you can experience a sudden loss of control without any warning whatsoever. Changing the steering rack can be a complicated process, and should only be attempted by a skilled mechanic.
