Suspension and steering: classic handling

Suspension Nissan Sunny B12 combines simplicity and efficiency. There are MacPherson struts installed at the front, and a semi-independent beam with trailing arms at the rear. This design provided good comfort and stability at high speeds, which was rare for budget cars of that time. Suspension stiffness can be adjusted by replacing springs and shock absorbers with more modern analogues.

The steering was mechanical, without power assistance, which required some physical effort from the driver when parking, but provided excellent feedback from the road. The steering mechanism was quite reliable, but wear on the steering rods and ends could lead to backlash and instability of the car on the highway. Steering rack in some versions it had a hydraulic booster, which made it easier to control.

When restoring the suspension, it is important not to skimp on silent blocks and anti-roll bar bushings. Their wear leads to knocking in the suspension and deterioration in handling. Using original spare parts or high-quality analogues will allow you to return the car to its factory characteristics.

• 🛑 Front suspension: check the condition of the CV joint boots and ball joints.
• 🔩 Rear beam: inspect the shock absorber mounts and the condition of the springs.
• 🔄 Steering: check the play in the steering shaft and the condition of the cardan.

Particular attention should be paid to the braking system, since braking efficiency directly affects safety. Rear drum brakes required regular adjustment of the gap between the shoes and the drum. Brake pads and discs should be replaced when the wear limit is reached, without waiting for squeaks to appear.
