Chapter 4 - Front Suspension and steering
123
ABOUT THIS CHAPTER:
Layout: There are three main sections of this chapter
1. The first section is concerned with identifying
problems in the front suspension and steering
system.
2. The second section covers correct adjustment
and alignment of the front suspension.
3. The third section covers component replace-
ment methods.
Approach: How the sections fit together
1. The first step in performing an alignment is to
check the basics. The tires should be properly
inflated, and all of the components should be in
good condition. Adjusting worn parts is a band-
aid solution to a more serious problem.
2. Most operational problems will show-up as align-
ment issues. Vehicles do not just “go out of
alignment”. Most alignment issues are the result
of identifiable wear or damage to specific com-
ponents.
3. Many times, damage will be obvious.
• In those cases, the technician can refer to the
component repair section of this chapter if they
need guidance in making a repair.
• After the repair is completed, a check of the
alignment is a handy way to confirm that the
damage is isolated to the obvious parts.
• As an example, if a technician repairs a tie-rod
end that was broken in a violent encounter with a
tree, the alignment should be correct when the
repair is completed. If the toe angle is not cor-
rect after the tie-rod end is replaced, it could
point to further, less obvious damage. If the toe
angle has changed because the steering arm
that is cast as part of the hub assembly has
bent, the hub casting should be replaced before
the vehicle goes back into service.
FRONT SUSPENSION & STEERING: INSPECTION
Adjustability:
• The toe angle and spring rates are adjustable on
the front wheels.
• Spring rates effect the camber angle.
• Spring rates and tire pressures should be
adjusted to suit operating conditions (load and
terrain).
Need for adjustment:
• Alignment should be checked whenever front
suspension or steering parts are replaced.
• If alignment needs adjustment but no parts have
been replaced or adjusted recently, check for for
worn or damaged parts.
• The remainder of this section details a pre-align-
ment component inspection.
Tire Inflation: See Figure 4.1.
Check the air pressure in the tires. They should be
between 14-22 psi (.97-1.24 bar.), and adjusted so that
the effective radius of the front tires is equal (same dis-
tance from hub center to ground) in normal operating
conditions.
