Like @Mophius said, you can’t align the rear axle (and if an alignment would point out it should be, the axle is f*cked, but let’s think positive 
)
The way torsion beam axles (the type of rear axle most Dai’s have) behave in corners is quite 
mysterious , abstract and in my opinion genius. It’s not a waterproof theory, but this could be the reason why it’s happening on just one side. See, the thing with torsion beam axles is that they gain camber and toe when the body rolls, in favor of handling. The outside wheel gains negative camber and toe out.
Right, so why would this matter? Well, my theory is that there’s always more weight on the left side, because of the driver. Maybe this changes the camber angles of the wheel (more negative camber left, less negative right) causing the body to roll a bit to the left, resembling a ‘corner’ (with a very big radius). Thus, giving the left side more clearance.
You’d have to do some very accurate measurements to prove this theory right, but you’d have to do the same to prove it wrong 
What do you gain from this? Nothing really. The easiest way to investigate is to try and find the spot where it rubs, to determine what needs to be done. If the tire is hitting the wheel arch, you could consider rolling your arches (pushing them outwards). If it’s something else, you might need another solution.
