My neighbor's rice burner has over 60k on it and the front end is just like new: totally tight, responsive.
My 98 'Burb has 160 on it and I'm on my third front end (tie rods, bushings, pitman arm, and so-forth) and this time, even a new steering box.
Seems like mine gets really loose by 60k. Mostly freeway driving, what off-road I do is 99% beach.
Different materials? Different design?
