:The most familiar form of this suspension was found in the early Corvairs and early Volkswagens. The differential unit was solidly mounted to the chassis and each wheel assembly pivoted at a universal joint near the differential. Major disadvantages were poor camber control and the possibility of "jacking," a situation where the outside wheel "tucks under," often resulting in the overturning of the vehicle. An alternate design eliminates one universal joint, with both wheels pivoting about the remaining universal joint. | :The most familiar form of this suspension was found in the early Corvairs and early Volkswagens.

:This modification of the swing axle described above provided a single pivot point...for both wheels...located below the differential, with provision for axial motion of the axles to prevent binding. | :This modification of the swing axle described above provided a single pivot point...for both wheels...located below the differential, with provision for axial motion of the axles to prevent binding. | ||
| − | + | 1.2.2.2. DeDion | |
:This design combines the excellent camber control of the beam axle with the reduction of unsprung weight and elimination of driveshaft torque features of the fully independent rear suspension. <br> The differential unit is solidly connected to the chassis and two universal joints and a splined connector are used with each axle. A single piece, usually consisting of a large diameter tube bent so as to avoid interference with the differential unit, connects the wheel uprights. | :This design combines the excellent camber control of the beam axle with the reduction of unsprung weight and elimination of driveshaft torque features of the fully independent rear suspension. <br> The differential unit is solidly connected to the chassis and two universal joints and a splined connector are used with each axle.
