Tire Alignment Question
 

I have alot of wheel noise coming from the front of my boxster and noticed that the front wheels have both worn down unevenly. They both have great tread until the inside part on both sides where it wore much more quickly. I figured that was the cause of my noise but I got new tires put on front today and even though it helped there is still some noise...I called porsche and they want 475 for an alignment! I went to Just Tires for an alignment but there machine could not fit my rims...anyone know where I can get an alignment for cheaper on this thing?

It ended up being my front passenger side wheel bearing causing all that noise...with only 42K it seems odd that would fail so early on...
