  1. Filed Sep 6, 2022Failure Sep 6, 2022Lefroy, ILSteering

    Noticed the steering linkage had an unusual amount of free play, Thinking it might be the bearing had failed. Bought a new part and had the one on the truck taken apart. When it was removed, it was noted that the linkage was not installed correctly. There is a safety bolt that locks the linkage and prevent it from dislodging and it was installed but not in a way to prevent separation from the steering linkage from the steering wheel. In one of the pictures where i took the linkage and attached it the way it was installed on the truck to demonstrate how it was. All in all, about 1/4" of splined shaft was holding this steering wheel in place as you can see in the wear from the parts.
