Suspension Maintenance

Rear Slide Wear

For ease of inspection, all POLARIS rail slides have a wear limit indicator groove to indicate the minimum permissible slide thickness. Replace the rail slides if they are worn to the top of the groove at any point along their length. Failure to do so may result in permanent damage to the track or rails.

Suspension Inspections

Loose nuts and bolts can reduce your snowmobile’s reliability and cause needless repairs and down time. Before beginning any snowmobile trip, a visual inspection will uncover potential problems. Check the following items on a weekly basis or before any long trip:
  • Check suspension mounting bolts for tightness.
  • Check rear idler wheel bolts for tightness.
  • Check rear idler adjusting bolt locknuts for tightness.
  • Check front torque arm limiter strap condition.
  • Check rail slide condition.
  • Check track tension.
  • Lubricate/grease all suspension components.
  • Check ski runner/skag condition.
  • Check ski spindle bolts for tightness.
  • Check tie rod end nuts for tightness.
