There are six types of factors affecting in steering are as follows:

1. Steering gear ratio and back lash.

2. Steering linkage connection.

3. Type pressure.

4. Condition of king pins and bushings.

5. Wheel alignment.

Ø Steering gear ratio: the steering gear provides mechanical advantage for the driver to guide the vehicle by exerting only a small amount of physical effort at the steering wheel. Steering gears usually have a mechanical advantage of 12 to 1and higher.

Ø Steering linkage connections: They must provide free movement of the linkage to transmit driver’s effort at the steering wheel to the knuckles. If there is more play in the joints, most of the efforts shall be going waste and if there is less play, hard steering would result in.

Ø Type pressure: It should be as per specifications. less or uneven pressure of air in the wheels shall result in hard steering and more tyre pressure shall lead to wobbling.

Ø Play in wheel bearings: The wheel bearing should be properly adjusted. Less play shall result in hard steering and more play shall effect wheel alignment and lead to wheel wander.

Ø Condition of king pins and bearings: The front portion vehicle load acts through the pins. If the pins. If the pins are tight in the bushes, hard steering shall result in and if there is more play, wheel alignment shall be affected, which has great influence on the steering operation.
