If more than two joints are used in a steering system, a support bearing must be used to prevent "looping" and binding. Use of a vibration reducer and two u-joints will also call for a support bearing to be used. A system with a double u-joint and a single u-joint has three flex points and will require a support bearing. Support bearings will work with all 3/4" splined or Double D steering shafts.

They are available in steel, stainless steel and polished stainless steel.
