Why don't you take it to the DEALER to see if your alignment is correct?
In my experience I can pay an indy today, tomorrow, and the next day and the alignment will never be correct!! You can change every part of the suspension or just the struts, but if its not aligned correctly, it will still more sensitive to winds that it should be.
Please see my other posts in this thread about toe-in & wind. IF it were my money I'd go to the dealer. If they don't find the alignment a problem, they may tell you something about worn parts your indy missed. I know people that use the Sac dealer for alignments with excellent results.
