well..mine squeek and creek when i go over large bumps and holes slowly (ie construction areas or dirt roads) plus its bouncier.

 

if you have a bouncy ride, they're probably blown...also, check your tire wear, if they've been blown long enough, you'll start to get weird tire wear (the tire tread will basically go up and down)

 

pull off your wheel and look for obvious leaks also.

 

could be blown...my friends cl was like that...unless u just installed springs.....

 

yea, that's funny that you mention this because I just got my Progress springs installed, and now my car is a lil more bouncy. I'm also hearing some strange rattling noises from the rear of my hatch when I go over bumps n stuff. I think it's the spare in there rattling around, but I have yet to check it out.
