From the schematic they should be ] [.

Don't think it really matters does it ? the bush is central in the arm.

Pretty sure it is A. ] ] from factory.

Don't know if the orientation matters though. Maybe [ will pick up more dirt and crud?

The part diagram might be different from the factory fitment sometimes.

It may matter. The wheel can move forward and back and these arms help prevent that. The design of the arms may be stronger in one direction than the other so they MAY flex more in one direction than the other. This could cause increased tyre wear, less sharp handling, increased wear on the bushes or (less likely) lead to fatigue cracking in the arms.

I do NOT know if the arms are designed like this but I do suspect that they are and that they should probably be fitted as biddyrascal has suggested. In my mind the only correct alternative to that would be []. Though none of this is from fact only my own interpretation of the drawing and my thoughts on this.

Best example of differing resistance to bending moment I can give is with a piece of angle iron. If you hold it with each side at 45 degrees to forces applied it is much easier to bend in one direction than the other. eg. a 25mm angle can be easily bent around my knee in one position but not in another.

The transverse arms do not prevent fore and aft motion of the wheel. The arms are designed to located the wheel in the side to side position. The front-back position of the wheel is located by the trailing arm.

They are fitted ] ] this way from factory and probably is the way it was originally designed to be fitted.
