How do you determine steering ratio?
Steering ratio is the angle need to turn the steering wheel for one 1 degree turn of the tyres. For example, if the steering wheel is turned 20° and the front tyres only turn 1°, that gives a steering ratio of 20:1. For modern cars steering ratio is between 12:1 to 20:1.
What is the steering ratio for heavy vehicles?
The ratio between input angle to output angle of the steering gear can be fixed or variable and is usually around 20:1. Also, the steering gear is hydraulically assisted, meaning that it will have a certain characteristic between the input and output torque.

We strongly encourage this service after the vehicle odometer has reached 60,000 miles. As your car continues to age its also a good idea to have it done every 30,000 miles thereafter. Considering that the average steering repair costs between $600 and $1000, routine preventative maintenance is a sound investment.

Is it bad to turn the steering wheel all the way?
You can turn it all the way, but don’t keep pressure on it, that strains the whole power steering system. You will hear the pump growl and the power steering hoses will stiffen up and the fluid will rapidly overheat. Not good. Turning all the way is OK once in a while when steering in a tight spot.
