How to Install a Ski-Doo Trailing Arm

Trailing arms are part of a snowmobile's suspension system. When viewed from above, the two trailing arms -- left and right -- point back in a sort of inverted "V" shape. Ski-Doos use these trailing arms as part of the system's suspension. Installing a new trailer arm is a straightforward process that takes about 30 to 60 minutes per arm. After you install new trailer arms, it is a good idea to do a ski alignment to 1/8 inch to ensure proper steering.

Instructions

    • 1

      Bring the Ski-Doo up and onto the jack. Lift the front end of the Ski-Doo. Use an adjustable wrench to remove the old trailing arms.

    • 2

      Apply a generous amount of grease to the bushings on the Ski-Doo -- where the trailing arms insert.

    • 3

      Slide the new trailing arm over the bushings. Tighten the bolts with the adjustable wrench or the dedicated trailing arm tool -- provided by some arm makers.

    • 4

      Apply superglue to the nuts on the arm bolts, to ensure a solid connection. Let it dry.
