Lesson 1/Learning Event 3
Learning Event 3:
The steering gear is one of the most used controls on the vehicle. If the
steering operates improperly, the operator loses no time in reporting the
problem because a faulty steering gear is a gamble with life.
As a wheeled vehicle mechanic, you are responsible for some of the
maintenance on steering systems. This maintenance includes troubleshooting
and minor repairs on the steering gears.
Another maintenance function you are responsible for is inspecting the
overall condition of steering gears. This is probably the most important
maintenance function of all.
COMMON STEERING PROBLEMS
Steering systems, like all mechanical parts, develop various problems. Some
of these problems are "unwanted factors" that affect the steering. Examples
of these factors are wandering, shimmy, and hard steering. As a wheeled
vehicle mechanic, you must know how to locate the causes of these problems.
Not all steering problems are caused by the steering gear.
Hard steering causes the operator to have trouble turning the wheel and
causes the operator to have to fight the wheel to keep traveling straight
down the road. It can be caused by lack of lubrication, bent parts, and
This is caused by steering parts that are worn, broken, or out of
adjustment. The driver must turn the wheel excessively to steer the
The vehicle wanders over the road. A vehicle should travel straight down a
level road with little or no guidance by the operator. If the vehicle
wanders, the operator must continuously turn (fight) the steering wheel to
keep the vehicle traveling straight.
