a strut holder configured to hold an end of the strut, wherein the strut holder is movably connected to the translational bearing surface, further wherein the translational bearing surface is configured to permit the strut holder to move in a first translational axis and to constrain the strut holder from moving in a second translational axis that is transverse to the first translational axis or a third translational axis that is transverse to the second translational axis; and

an electromechanical actuator mounted on top of the upper mount body and coupled to the strut holder to drive the strut holder along the translational bearing surface in the first translational axis.

2. The device of claim 1 , further comprising an electronic controller configured to control actuation of the electromechanical actuator.

3. The device of claim 2 , wherein the electronic controller is configured to adjust toe of the vehicle when adjusting camber.

4. The device of claim 1 , wherein the translational bearing surface comprises a pair of shafts extending in parallel on either side of the strut holder.

5. The device of claim 1 , further comprising one or more linear bearings that are rigidly connected to the strut holder and movably connected to the translational bearing surface.

6. The device of claim 1 , wherein the electromechanical actuator comprises an electric motor coupled to the strut holder to move it in the first translational axis.

7. The device of claim 1 , wherein the electromechanical actuator comprises a ball screw and a ball nut, wherein the ball nut is coupled to the strut holder and is configured to be driven back and forth along the ball screw.

8. The device of claim 1 , further comprising an encoder configured to monitor the position of the strut holder.

9. The device of claim 1 , wherein the translational bearing surface is configured to support a radial load of greater than 1500 kg.

10. A device for adjusting camber of a vehicle having a suspension including a strut, the device comprising:

an upper mount body and a lower mount body configured so that the vehicle's frame may be secured between the upper mount body and the lower mount body with an opening on the upper mount body aligned with an opening on the lower mount body, wherein the lower mount body comprises a translational bearing surface;

a strut holder configured to hold an end of the strut, wherein the strut holder is movably connected to the translational bearing surface, further wherein the translational bearing surface is configured to permit the strut holder to move in a first translational axis and to constrain the strut holder from moving in a second translational axis that is transverse to the first translational axis or a third translational axis that is transverse to the second translational axis;

an electromechanical actuator mounted on top of the upper mount body and coupled to the strut holder through the opening on the upper mount body and the opening on the lower mount body to drive the strut holder along the translational bearing surface in the first translational axis; and

an electronic controller configured to operate the electromechanical actuator.

11. The device of claim 10 , wherein the translational bearing surface comprises a pair of shafts extending in parallel on either side of the strut holder.

12. The device of claim 10 , further comprising one or more linear bearings that are rigidly connected to the strut holder and movably connected to the translational bearing surface.

13. The device of claim 10 , wherein the electromechanical actuator comprises an electric motor coupled to the strut holder to move it in the first translational axis.

14. The device of claim 10 , wherein the electromechanical actuator comprises a ball screw and a ball nut, wherein the ball nut is coupled to the strut holder and is configured to be driven back and forth along the ball screw.

18. A device for adjusting camber of a vehicle having a suspension including a strut, the device comprising:

an upper mount body and a lower mount body configured so that the vehicle's frame may be secured between the upper mount body and the lower mount body with an opening on the upper mount body aligned with an opening on the lower mount body, wherein the lower mount body comprises a translational bearing surface formed by one or more shafts;

a strut holder configured to hold an end of the strut, wherein the strut holder is movably connected to the one or more shafts forming the translational bearing surface by one or more linear bearings so that the strut holder moves in a first translational axis and is constrained from moving in a second translational axis that is transverse to the first translational axis or a third translational axis that is transverse to the second translational axis;

an electromechanical actuator mounted on top of the upper mount body and coupled to a center region of the strut holder through the opening on the upper mount body and the opening on the lower mount body to drive the strut holder along the translational bearing surface in the first translational axis; and
