I took my car in for the same issue. It ended up being the Left LCA, they said they're going to replace both. The Left LCA came in, it took them two days to tell me the Right LCA is on backorder with a To Be Announced date. They did give me a rental this entire time, it seems like a waste to give me a rental when you don't even know if the hardware will be in or not. I'll be dropping my rental off on Saturday to get my car back (unless it comes in tomorrow, most likely not), then bring it back again when the parts come in. It's about an hour away from my house also.
Make sure they have the parts in before taking your car in. I lived and learned.
