Two-piece bushing for a commercial vehicle

A method for installing a steering assembly for a vehicle, comprising:

• providing a housing configured to be mounted to a chassis of the vehicle, at a firewall between a driver cab and an engine bay of the vehicle, wherein the housing defines a first through hole connecting the driver cab and the engine bay;
• providing a top cap defining a second through hole mounted on the housing on a side facing away from the firewall, the top cap and housing defining a chamber therebetween;
• providing a steering shaft disposed in the first and second through holes, having a first end mechanically coupled to an upper steering shaft, and a second end mechanically coupled to a lower steering shaft,
• wherein a portion of the steering shaft within the first and second through holes includes an upper groove and an axially spaced lower groove each circumferentially surrounding the steering shaft;
• and
• providing an annular two-piece bearing disposed in the chamber and circumferentially surrounding the steering shaft, the annular two-piece bearing having:
• an upper lip engaging with the upper groove, and a lower lip engaging with the lower groove;
• a convex outer surface abutting an inner wall of the chamber;
• an inner convex surface that abuts the steering shaft,
• wherein the annular two-piece bearing is configured to limit an axial movement of the steering shaft during operation of the vehicle and to permit rotation of the steering shaft.
