Suspension problem...

[gorgasm]

So I jacked the car up on the left side where i thought the problem was coming from, the rear left shock to be exact, (when i reverse, come to a complete stop, downshift, or do anything that puts stress on that area, i hear a loud CLUNK that sounds like its coming from the trunk area... and when i hit bumps the back of the car pulls to the right and it makes that clunking sound, which makes freeway driving pretty scary) and so after getting the left side in the air I started pulling up on the rim and letting it go to see if i could simulate the shock contracting over bumps... and i realized the shock is very weak and easy to compress... and when i let it go i hear the loud thump in the trunk... to confirm that this wasnt normal i jacked up the right side and did the same, it was harder to get the shock to compress and when i released it it made no noise... So what I am led to believe is a have a blown shock.. but would a blown shock cause the car to pull to the right when I hit bumps? Im thinking possibly the alignments off so the shock could be the problem... Do you think its anything besides the shock? .. Any help for a noob is appreciated.. thanks guys.
