Took the '03 in for a tire rotation and the guy taking it back said it felt horrible and had a pretty big "knock" in the suspension. I've been noticing it too, being I don't drive this car as often, but the rest of the family just dismissed it as being related to it "just being a big SUV, it's not supposed to handle well". But now that someone else has mentioned it, they're taking it a bit more seriously. Basically there is a lot of play in the steering and some feathering on the inner side of the tires, which only have 4,000 miles on them. Front only. The tire guy suggested that it was the ball joints. And with 126k miles without any suspension work ever done, I suspect they're due for replacement anyway. What's the average rate for a replacement, with me doing the work myself, and where should I get the parts? Also, what should I be looking at replacing in the near future? The service ride control message is on, so I know I'm looking at some serious stuff. Thanks guys.
