  1. Without detaching the torque arms, use your hand to attempt to move each of the radius rod ends up, down, in, and out. If there is any movement, replace the torque arm.
  2. Inspect the weld seams between the torque arm tube and the shorter bushing tubes. If there are cracks, replace the torque arm. Do not weld the torque arm for any reason.
  3. Inspect the rubber bushing ends. See Fig.. Replace the torque arm for any of the following reasons:

    • There are gaps between the rubber bushing and the pin or the outer steel sleeve.

    • Either bushing end contacts a torque arm pin mounting bolt.

    • There are cracks in the bushing.

    • Part of the rubber bushing extends beyond the outside diameter of the outer bushing sleeve.
