Checking the Torque Arm Bushing, Freightliner AirLiner
sb mm 32.11.001
- Without detaching the torque arms, attempt to move (by hand) each of the rod ends up, down, in, and out. See Fig.. If there is any movement, replace the torque arm.
- Inspect the rubber bushing ends. Replace the torque arm
if there are gaps between the rubber bushing and the pin or the outer
steel sleeve. If either bushing end contacts a torque arm pin mounting
bolt, if there are cracks in the bushing, or if part of the rubber
bushing extends beyond the outside circumference of the outer bushing
sleeve, replace the torque arm.
