Cadillac-LaSalle ride.
In Cadillac Knee Action each front wheel is fastened

transferred to the steering system. This eliminates car
wander and shimmy. Steering is much less affected in
event of tire blowout at high speeds. Caster angle is not
affected by brake or spring action.

frame. Front frame arms encircle the helical coils on
