STEERING
INSPECTION
Prior to performing steering alignment, inspect all steering and
suspension components for wear or damage and replace parts as
necessary. Refer to steering assembly exploded views in this
chapter for identification of components and torque values of
fasteners. While disassembling, make notes of what direction a
bolt goes through a part, what type of nut is used in an
application, in which direction do the steering arms go on - weld
up or weld down, etc.
Some of the fasteners used in the IFS are special and cannot be
purchased at a hardware store. Always use genuine Polaris parts
and hardware when replacing front end components. Review
steering adjustment guidelines before making adjustments.
The following components must be inspected at this time.
• Tie rods and tie rod ends
• Control arms and control arm ends
• Torsion bar and bushings / linkage (where applicable)
• Handlebars and steering post assembly
• Spindles and bushings
• Skis and skags
• Pitman arms / Idler arms
• Steering arms
FRONT SUSPENSION & STEERING
• A-arms and bushings
• Shock absorbers, shock mounts, springs
• All related fasteners - check torque. Refer to steering
exploded views at the beginning of this section.
• Grease all fittings.
Always follow rod end engagement guidelines. Maximum
setup width must be checked whenever front suspension
components are adjusted or replaced.

Camber Definition

The following definitions of camber use automotive
terminology to describe positive and negative positions.
• 0 = Neutral camber. The spindle is 90° (perpendicular)
to the ground.
• + = Positive camber. The bottom of the spindle is
canted inward toward the chassis.
• - = Negative camber. Spindle bottom is canted outward
from the chassis.
