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
• Radius rods and radius rod ends
• Torsion bar and bushings / linkage (where applicable)
• Handlebars and steering post assembly
• Spindles and bushings
• Trailing arms and bushings
• Skis and skags
• Pitman arms / Idler arms
• Steering arms
• 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.
