Every time I go over an incline at an angle or hit a bump in the road, I hear a creaking-type sound coming from the front-passenger side... when I get out of the car, I can hear the creaking if I push the body down and then let it up on the passenger side over the wheel - no noise when I do it on the driver side - is my shock to blame?

ps the only suspension mods I have are the hotchkis springs...

 

they could just be loud springs or the plastic dust cover is cracked. you can generally see oil on your shocks if they are shot.
