...well I don't think I can do it myself; the reason I want to change it is because I read more stories about them breaking at 90-100K than lasting all the way to 130K. I don't have a trusted shop so I always go to the stealership and pay extra for the peace of mind. I am aware of the belts and all that.

Is there a DIY for it? Perhaps if I take a look at the pictures I may adventure myself, the thing is, I would not know how to re-tension the belts, that's my biggest "fear".
