i don't know where this noise is coming from. and i have no idea what it means. when i shift gears sometimes though and i accidentally let off the clutch a little early and the car jerks a bit, there's a funny thunking noise. if i go over a speedbump without going VERY VERY VERY carefully there's a really LOUD thunk. any ideas?

is my suspension blown or something? there's just way too much squeaking and thumping going on for it to be normal. ALSO, my steering wheel...makes a HISSING noise when i turn it. it used to only make a groaning/hissing noise when i started it up. but now it's just all the time. checked the fluids and everything. no air in the system...should i just trade my darn car in for a new one...err...can't afford...to fix every freaking week.
