There is 2 metal lines that run up and over the driver side wheelwell . What are these lines ? I am seeing a sheen on the ground and it looks like it may be coming from these 2 lines where there is a foam separator on the wheelwell and it looks like it has rusted out in this area . Are these power steering cooler lines ? Hopefully it is not the cooler itself too . What are we looking at pricewise if these have to be replaced at a garage ? Thanks for any info .
