The Datsun 1200 uses a traditional recirculating-ball Steering Gearbox with parallelogram behind-the axle Steering Linkage. USA models used a Collapsible Steering Column to meet FMVSS standards, while most other countries got a rigid Steering Column. The steering action in a stock vehicle should be very light with a fast action. Wide tires will increase the amount of effort needed to turn the wheels. The steering linkage needs lubrication on a regular basis.

Maintenence
The Factory Service Manual advised checking the gearbox oil every 10,000km or six months and topping up as needed. However unless the gearbox is visibly leaking, checking every 15,000 miles twelve months should be sufficient.
The Steering Linkage needs to be "lubed" at regular intervals. Nissan recommends every 50,000km (30,000 miles). I recommend doing it annually. If you take it to a service shop, ask for a "lube and oil change".
The bushing at the Steering wheel end of the column is the part most likely to go bad. It causes a squeak, squeak sound when you move teh steering wheel slightly.

For minor play in the steering wheel, you can perform a Steering Gearbox Adjustment. For major play in the wheel or wandering, check out the linkage. See Steering Gearbox Adjustment for details.
Finally, after many miles the gearbox may need replacement. See Steering System Diagnoses.
