Coupling-Steering, Lower

The steering column lower coupling connects the steering column shaft to the steering gear input shaft. Working with a universal joint located on the end of the steering column shaft, the steering column lower coupling allows for the misalignment of the steering column with the steering gear.

There is a single-stage collapsible sliding joint located near the center of the lower coupling intermediate shaft. It collapses (shortens) with approximately 30 lbs. (14 Kg) of force applied lengthwise, such as when the vehicle is involved in a front end collision involving the steering gear.

The collar mounted near the center of the shaft is there to provide a clean surface for the dash seal to ride upon, sealing the gap between the shaft and the dash panel.
