How do you know shocks/struts are blown?

Yeah, i figured I would. wouldnt hurt anything, thats for sure!
I'm going with the Bilsteins...but there's been a few things holding me back later:

1) Built a bar from scratch, had to buy tools and everything
2) Bought a 42" flat panel LCD
3) My clutch started acting up yesterday. Hasn't gone completely out yet, just loud creeks, squabbles, cries, moans, squeaks, and grunts.

But I have my mind set on the Bilsteins...heard that they are 1 of the 2 best brands for the Super Sports. Other brand I heard is the Tokicos.
 
When my front right strut was blown, every bump no matter how small sounded like the front of the car was going to die. You couldn't even tell with the whole pushing on the corner to see how it bounces trick, but you could hear it plain as day. My rear left spring was also snapped in half too though.
 
Actually I got Gabriel dampers at AutoZone. They were $18 for each shock and $38 for each strut. They lasted a good 18 months or so if you want a temp fix get Gabriel or even better Monroe. If you want the final solution go with Bilsteins. I also agree that Tokioco is good. The stockers are actually Tokioco made to a special crappy Ford spec just for the assembly line. But aftermarket Tokiocos are acceptable.
 
I went a bit cheap on my first try. Went with tokico drag struts. Well about a year later, I turn and hit my breaks...CLUNK. Left front strut snapped in half! It had also went bad about a week before, and was leaking fluid.

I ditched the drag approach, went with 275# springs vs 175#, and switched to the HD Bilsteins. Couldnt be happier! Bilsteins ROCK!
 
If you push down, say on the front quarter panel (don't dent it) and the car comes back up and then rests, the shocks are fine. If the car bounces more than once then your shocks are poo. Thats a general way to tell ...
