I own a 2012 Frontier with about 86,000 miles on it. I believe I need an alignment because of some symptoms I've noticed. Firestone repair shop told me that they have to buy some extra part because of the way Nissan cut corners on the Frontier and it would cost about $450 to do the alignment. That sounds fishy to me. Does anyone know what he's talking about? One more thing. Because of the trucks rear axle, the Frontier only needs a front end alignment, right? You can't do a 4 wheel alignment on this vehicle?
