Steering System
The steering system consists of a power
steering pump, gearbox and reservior.
WARNING!
Do not operate the vehicle if the steering
system is not working properly. You could
lose control of your vehicle if the steering
system is not in good working condition,
which could result in a serious accident. For
driving safety, visually check the steering
gear and components. Frequent checks are
important for driving safety, especially after
traveling over rough roads. Failure to com-
ply may result in death, personal injury,
equipment or property damage.
WARNING!
If this chassis is equipped with an electronic
stability system (ESC) and any part of the
steering system (e.g., linkage, steering
driveline, column, front end alignment, etc)
is repaired, removed, or disassembled in
any way, or if the steering angle sensor is
replaced, the steering angle sensor must be
recalibrated. Any repairs or adjustments to
any part of the steering system must be per-
formed by an authorized dealer. Failure to
comply may result in death, personal injury,
equipment or property damage.
Oil (under low pressure) provides the
power to operate the steering gear. It also
serves to lubricate moving parts and
remove heat. A loss of steering efficiency
will occur if too much heat builds up in the
system.
If the steering feels unbalanced from side-
to-side while turning, check for the
following possible causes:
• unequal tire pressures
• vehicle overloaded or unevenly
distributed load
• wheels out of alignment
• wheel bearings improperly adjusted.
If you cannot correct the problem, check
with an authorized dealer.
Your vehicle is equipped with integral
power steering. The system includes an
engine-driven fluid pump, a fluid reservoir,
the steering gear, and connecting hoses.
Because of the hydraulic power assist, little
effort is required to turn the steering wheel.
When no input is applied through the
steering wheel, the steering gear will return
to the neutral position. If, for any reason,
the power assist system goes out, steering
the vehicle is still possible, yet it will require
much greater effort.
Visually check the following parts:
• Crosstube: Is it straight?
• Draglink tube clamp: Check for
looseness or interference.
• Ball joints and steering U-joints:
Check for looseness.
• Steering wheel for excessive free-
play. Check the simplest probable
causes first: a. unequal tire
pressures b. loose cap nuts c. bent
crosstube d. lack of lubrication.
If these checks do not reveal the problem,
or if you correct them and still have a
steering problem, take your truck to an
authorized dealer for evaluation.
