How to programmatically rotate 2D GameObject with SliderJoint2D Attached

I have a Game Object with SliderJoint2D attached. Now I am trying to rotate the object using :

rigidbody2D.MoveRotation(rigidbody2D.rotation + rotationSpeed * Time.deltaTime);

Everything works correct, no errors, no warnings, but when I press the button GameObject does not rotate when Slider Joint is attached. When I try the same code with slider joint disabled, it works, but the problem is that I need my object to slide vertically.

I also tried to disable slider joint and keep my object sliding using this code:

Vector3 tmp = transform.position; tmp.x = 0; transform.position = tmp;

But in this case I am getting horrible problem with my wheel joints they just start to move in a very crazy and abnormal way.

You are welcome to suggest solutions for both cases: Or how to rotate object with slider joint, Or How to fix the wheel joints crazy movement.

Thank you in advance! :)
