Tell him you bought a fresh set of exhaust manifold heatflap springs, which you were told would keep all seals on your vehicle working better than before.
I bought the lifetime firestone alignment thing. I took it in several alignments ago and they said that they couldn't do it since I needed new ball joints. I know they aren't in the best of shape, but they are tight and well greased. I told them to give it their best shot and we'll go from there. I picked it up and there was no mention of ball joint work recommended. Several alignments later, still no suggestions for new ball joints.
