Steering System
WARNING
DO NOT operate the vehicle if the
steering
system is not working proper-
ly. You could lose control of your vehi-
cle if the steering system is not in good
working condition, which could result
in a serious accident. For driving safe-
ty, visually check the steering gear and
components. Frequent checks are im-
portant
for driving safety, especially af-
ter traveling over rough roads. Failure
to comply may result in personal injury,
property damage, or death.
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 re-
placed, the steering angle sensor must
be recalibrated. Any repairs or adjust-
ments to any part of the steering sys-
tem must be performed by an author-
ized dealer. Failure to comply may re-
sult in personal injury, property dam-
age, or death.
Hydraulic fluid (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 but it will require
much greater effort.
Visually check the following parts:
• Crosstube: Is it straight?
• Drag link tube clamp: Check for
looseness or interference
• Ball joints and steering U-joints:
Check for looseness
