Part fits Carraro axles. If in doubt, check the axle nameplate number on your machine.
The lower trunnion works with a tapered roller bearing, seal, and grease nipple. Replacing this part often involves replacing the knuckle bearings. Also check the condition of the upper trunnion.
Trunnion fracture or extreme knuckle bearing wear can lead to the wheel falling off while driving or working. This manifests as significant wheel play ("flapping") and oil leaks from the knuckle. Do not ignore these symptoms!
The lower trunnion is the pivot axis of the steering knuckle, transferring the machine's weight to the wheels.
