I'm guessing it isn't your struts, I'm guessing it's your brakes. My car was riding like **** last week... and on monday I worked on it a little. Here's what to do, to hopefully save yourself some scratch:
1. Jack up the car, remove the wheels (or do this one at a time)
1.5. Pop the hood, loosen the brake fluid cap
2. Take the 12 mm bolt outta hte back of the caliper
3. Swing up the caliper
4. Take out the pads
5. Apply 'disc brake anti squeal compound' to the backs of the pads... a lot on the outboard side, a bead on the inboard side
6. LET THE COMPOUND SET, do NOT install it if it's still wet and not very hard. Wait until it is tacky and rubbery.
7. While waiting for the compound to set, look behind your brakes, by sticking your head in the wheelwell. See those two bolts that attach the caliper to the dust/gravel shield/brake backing? They're 17 mm if I recall correctly. Anyway, see them? See how they're tight?
8. They probably aren't tight. WRENCH THE HELL OUT OF THEM. Turn them until you strip em, then back off a little.
Just kidding, but seriously, they're tough, don't be afraid of them. TIGHTEN THE PISS OUT OF THEM.
9. Reinstall the pads.
10. Put everything back together
Take it for a test drive. WOW. It's like driving a new car. WOW.
