| − | * | + | *The two carden joints are out of phase 90 degrees. It may work but not without unnecessary movement. |
*The Heim intermediate bearing is redundant. If the top shaft bearing is adequately rigid and the steering box is obviously rigid, the Heim bearing will only serve to add stress to the system. It is impossible to perfectly line up three in-line bearings and this added constraint will add stress. May be minimal but is a negative. The bearing is not needed; intermediate bearings are not called for in a two U-joint drive shaft. | *The Heim intermediate bearing is redundant.
