I had the same problem; a bent lateral arm due to getting hung up a rock in a snowy driveway last winter. It was indeed causing a slight wear on the inside of the driver rear tire.

I found a pair from another member here and replaced them both. The only trouble is that while removing the old link bolt (the long bolt that connects both lateral arms together), you may end up ruining the lateral arm bushings. So, keep that in mind and plan for it.
