TROUBLESHOOTING (SKI, SUSPENSION)
This section will point you towards possible solutions for resolving handling or ride comfort com-
plaints. When making adjustments, do it in a small increments. Also, in general, making just one
adjustment may not correct the problem. You may need to make several small adjustments to get
the best overall results.
Keep in mind that how the snowmobile handles going down the trail is usually controlled by the front
suspension, the center shock, and the limiter straps. How the snowmobile rides (ride comfort) is
usually controlled by the rear shock.
Also, remember that snowmobile suspension adjustments may involve compromises. Tuning a
snowmobile to do one thing very well may come at the sacrifice of something else. For example, if
the snowmobile is setup to provide optimum weight transfer for best acceleration, this same setting
will not be ideal for trail riding, because excessive under steering may be experienced during cor-
nering. You must have a good working knowledge of the suspension and tune the suspension to
provide best overall balance for specific conditions and usages.
SYMPTOM DESCRIPTION
POSSIBLE CAUSE
POSSIBLE REMEDY
Front of the snowmobile darts
from side to side on a straight-
away.
• Too much weight on skis.
• Extend limiter straps and/or
increase center shock spring
preload or reduce rear shock
spring preload or reduce front
shock spring preload.
• Skis out of alignment.
• Adjust “ski-toe-out.”
• Loose steering ball joints.
• Replace worn ball joints.
• Too much carbide on ski run-
ners.
• Use ski runners with less car-
bide.
Under steering – front end
(skis) pushes when cornering.
• Worn or missing carbides on
ski runners.
• Replace carbide runners.
• Not enough weight on skis.
• Reduce center shock spring
preload and/or shorten limiter
straps. Increase front shock
spring preload.
Over steering. Front end (skis)
bites too much during corner-
ing – rear of the snowmobile
starts to come around.
• Too much weight on skis.
• Extend limiter straps and/or
increase center shock spring
preload or reduce rear shock
spring preload or reduce front
shock spring preload.
• Too much carbides on ski run-
ners.
• Use ski runners with less car-
bides.
Heavy steering – excessive
force is needed to turn the
handlebars.
• Too much weight on skis.
• Extend limiter straps and/or
increase center shock spring
preload or reduce rear shock
spring preload or reduce front
shock spring preload.
• Too much carbides on ski run-
ners.
• Use ski runners with less car-
bides.
• Steering linkage binding.
• Clean and lubricate steering
ball joints and column.
