Toe Alignment

Use the following procedure to check the toe alignment of the vehicle. 

The recommended toe alignment is 1/8" to 1/4" (3-6 mm) toe out.

WARNING! Severe injury or death can result from improper toe alignment 

and adjustment. Do not attempt to adjust tie rod alignment. All tie rod 

adjustments should be performed by an authorized POLARIS dealer or other 

qualified service facility.

1. Position the vehicle on a level surface.
2. Set the handlebars in a straight-ahead position and secure them in this 

position.

3. Place a chalk mark on the center line of the front tires approximately 10" 

(25.4 cm) from the floor, or as close to the hub/axle center line as 

possible. Make sure both marks are the same distance from the floor.

4. Measure the distance between the marks and record the measurement 

(1).

5. Move the vehicle to rotate the tires 180°. Position the wheels with the 

chalk marks at the rear of the tires, even with the hub/axle center line.

6. Measure the distance between the marks and record the measurement 

(2).

7. Subtract measurement 2 from measurement 1. The difference is the 

vehicle toe-out alignment.

If you discover improper alignment, see your POLARIS dealer for 

service.
