For the front, the main problem lies with the lower control arm bushings, then the ball joints, then the tie rods, then the control arm itself (the inner ball joint isn't replacable, so you need a whole control arm). Check the upper strut mount too, but I don't hear of them wearing out too quickly.
For the rear, toe arm bushing and shock mount mainly, and check the diff and subframe mounts/bushings while you're there. The other bushings in the rear go too, but not as common.
If you're going to replace your bushings, and you don't drive in the extreme cold, swap the bushings with urethane bushings, less flex, which is great for more aggressive driving.
"Driving is like a narcotic, an addiction that can take over lives. It ruins people, breaks families apart, and even kills. Itís habit that needs to be fueled. Time, money, rationality, sweat, knuckle skin, and anyone who disapproves are of little importance to a driver, and are often overlooked. Hi, Iím Nelson, and Iím a drivaholic."
