I need to replace the tie rod ends on my '04 XC90 T6 as the outer passenger one is going out. I was told that I actually need to replace both sides, which I have no problem with, but the mechanic said I need to replace the sway bar links too. I had a friend look at it who is a shadetree mechanic and he said he doesn't see anything wrong with the sway bar. My mechanic is saying that they have to replace at the same time and this jacks the bill up considerably because of the extra labor for the sway bar. So my question then is are they truly interconnected where everything needs to be replaced, or is my mechanic just trying to "upsell" me at this point?
