SPINDLE ASSEMBLY

1.

Replace the steering arm and torque the bolt (25) to 29 ft-
lb (39Nm).

2.

Replace the retainer ring (22) on to the lower portion of the
spherical bearing.

3.

Place the spindle onto the lower spherical bearing.

4.

Place the flanged nut (19) on the lower spherical bearing
bolt (24) and torque to 29 ft-lb (39Nm).

5.

Place the camber bolt (12) and torque the jam nut (14) to
35 ft-lb (47Nm).

LOWER SPHERICAL BEARING 
REPLACEMENT

1.

Remove the spindle.

2.

Remove the snap ring (22) form the lower spherical
bearing.

3.

Replace the lower spherical bearing (21).

4.

Replace snap ring (22).

5.

Install spindle.

6.

UPPER / LOWER CONTROL ARM 
REMOVAL

1.

Remove the spindle(s) and shock(s).

2.

Remove the upper and lower control arm(s) bulk head
bolts (1,6).

3.

Remove the upper or lower control arm (10,20) and
remove all pivot bushings (5,9), and all pivot shafts (7).

UPPER / LOWER CONTROL ARM 
INSTALLATION

1.

Replace the upper or lower control arm bushings (5,9) in
the control arm(s).

2.

Replace the upper or lower control arm(s) into the

bulkhead.

3.

Replace the upper or lower control arm bolts (1,6). Torque
to 40 ft-lb (54Nm).

NOTE:  The washer (2) is only located on the 
rearward lower control arm mounting, and should be 
located at the bolt head.

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.

FRONT SUSPENSION/STEERING

ALINGMENT BAR SPECIFICATIONS

• DIAMETER: .623”-.625” (15.824-15.875mm)

• LENGTH: 45” (114.3cm)

• MATERIAL: C-1018

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 spinde is canted 

inward toward the chassis.

• - = Negative camber. Spindle bottom is canted outward 

from the chassis.

ROD END PROCEDURE

Rod ends must be parallel to their respective mounting surface 
after tightening jam nut. Hold the rod end and tighten jam nut. 
If possible, support the edge of the rod end to keep it from 
rotating out of position until jam nut is tight. When rod ends 
are properly tightened, the rod should rotate freely 
approximately 1/8 turn.

ROD END ENGAGEMENT

Rod ends must engage the rod a minimum of 2x the thread 
diameter when adjustment is complete.

Example: .4375” (11mm) rod end (A) X 2 = minimum thread 
engagement (B) .875” (22mm).

CAMBER &TOE 
SPECIFICATIONS

The following table is the factory specifications for the 2006 
Polaris Snowmobile front suspension set up. 

Maximum width and camber measurements are to be taken 
with the front end elevated and shocks at full extension.

Toe alignment is measured at ride height. This means that the 
machine is on the ground and resting at normal ride height, not 
full rebound. Measure at a point 10” (2.54cm) forward of the 
ski mount bolt and 10” (2.54cm) behind the ski mount bolt, 
preferably on the center line of the carbide skags.

Width is measured from the center of the spindles.

Camber measurement is taken from the top of the alignment 
bar to the top of the ski mount hole in the spindle with the 
bushing removed.
