Let me start off: I drive this car HARD. The suspension also gets a hefty workout because the roads around here suck, and I've done some accidental mean things to it (like go over a long hump really hard... rail-road tracks at a moderate speed) and I drive like I'm auto crossing or running from the police. So there's obviously been some hefty wear going on.
Ok, I know I have some problems and a few failing\broken parts already, or at least something is loose. Tonight I hit a huge hump and afterwards, it felt like one of the front wheel's connection to the steering arms was loose, allowing the wheel to wobble back and forth. (I know this isn't the case because it'd be wobbling like crazy, esp. at 90 mph) [I'm in the country... empty highways nearly nobody around]
What could be the problem? Sway? Control arm bushings? (admitedly I don't know ^exactly^ what those two things are.) I know the alignment is messed up because when I turn, I can feel that the wheels aren’t lining up where they should be. (I know the inside wheel has to turn more than the outside, and it feels just like that). Everything just feels wrong.
It’s completely stock with 89k miles on it. (I’ve had it for 15k miles) Should I get new suspension soon? What does everyone recommend that I look for to replace and what extra should I do to my car (performance, I like turns

) Would most of this stuff be hard to do with a set of ramps + jackstands by myself or wtih a buddy? [we are both very mechanically inclined so I dont think it would be too hard] I havn't worked UNDER a car before
