So, I went in to get an alignment today from a little independent shop and to see if that would fix a shake in the steering wheel when going 60mph or more. They get everything back in spec for the alignment, but they told me that I need to rotate my tires (just done) and that my stock suspension (shocks) are causing the steering wheel to shake at higher speeds. They also told me Mazda wouldn't cover it with the factory warranty. I didn't believe that, but was curious if you have ever heard a shop say that the steering wheels shakes because of the stock or any suspension. The car has 18k miles on it. I could believe it if they said my tires needed to be balanced, but the suspension???? (confused) Doesn't make sense to me. What do you guys think?
