I had bushings replaced around those miles myself, and am having them done again on Monday with a secondary guy. The bushings themsevles are very cheap, the problems is they are very labor intensive, and then the car must be aligned...my local dealership sucks, so I'm not having them do that work. The stealer (at 109,000 miles) says I need new control arms and bushings. Not so sure about that, but they are quoting me $910 for both on left and right and $200 for alignment for both arms and bushings. I'm going to have my independent guy do the bushings and give me a recommendation on the arms on Monday.
The in-camashaft position sensor is like $99 and the out is maybe $85 for the parts. Not sure why they cost different amounts. The labor for the in is nothing, but my local dealer (stealer) somehow managed to charge me $359 to put in a $100 part. It is an easy DIY and I was kicking myself for allwing myself to be suckered. The out camshaft position sensor is more difficult to do, from what I understand (I'm no mechanic here).
Not sure if any of that helps, but there you go.
