If you're just having "looseness" in the front end, I'd start with replacing the struts. I have my OEM struts on still, but they've gone away a bit, and will be getting replaced later this year (I hope). I noticed the front end seeming loose on bumpy roads, and on really rough spots at any speed (bridge abutments, potholes, etc.) it can seem like it's wanting to get away from you, but it doesn't really do so, only hints at it. So I talked to my suspension guy, and he asked if I had any noises. I do, a slight popping sound when the suspension articulates in slo-mo (may be there at speed but can't hear it, it's so slight). He grabbed the front wheel and yanked on it top and bottom without any real play, and said, "Your struts are going." I asked him how he knew it was that and he said the wheel is stable, so the ball joints aren't gone, but the looseness and faint popping is the strut. I was a little surprised, but he said he'd bet the farm, and I trust this guy.
So I'd start with struts and go from there. You can always replace the ball joints and/or arms if need be, after you get the new struts on.
