Checking the free play (play) of the steering wheel (Mondeo 4)

With increased free play of the steering wheel, it is difficult to control the car, as it reacts to the driver's actions with a delay. In addition, increased play, which cannot be eliminated by adjusting the steering mechanism, indicates a malfunction of the steering (loose fastening of the steering mechanism, steering rods or wear of their parts).

Check the steering wheel play on the vehicle installed on a smooth, non-slip surface. The play should not exceed 5°.

You can also determine the play in linear units (mm) using the formula L = (5°/360°)pD, where L is the play of the steering wheel, mm; p = 3,14; D – outer diameter of the steering wheel, mm.

For example, for a steering wheel with an outer diameter of 380 mm, the play should not be more than 16–18 mm.

You will need: a ruler, chalk (or wire) for making marks.

1. Set the front wheels to a position corresponding to the straight-ahead movement of the vehicle.



2. Position the ruler so that its end rests against the instrument panel and the plane of the ruler touches the outer surface of the steering wheel rim. Without changing the position of the ruler, turn the steering wheel to the left until the front wheels begin to turn.



In this position, make a mark on the steering wheel rim (secure the wire).



3. Without changing the position of the ruler, turn the steering wheel to the right until the front wheels begin to turn.



4. In this position, apply a second mark on the steering wheel rim (secure the wire).



5. Measure the distance between the marks on the rim. It should not be greater than the calculated value. If the distance (steering wheel free play) is greater, it is necessary to determine the cause and eliminate it
