Sound from the bottom back

while the vehicle is walking, there is a cracking sound from the bottom rear wheels. it sounds like a metal, like a metal. just released. not doing all the time. Generally, the vehicle leaves the garden in the first movement in the morning, while doing full right or left left maneuver. why can this happen? how can it be solved? Where should I check?

I do not know that . how does he control it? when I turn to the right, I usually hear sometimes it does not come sometimes

When I looked under the vehicle, I saw an oil leak in the left rear shock absorber, it had dust on it, but can wet do this problem? How do we control the exhaust wedges?

How do I know if there is a problem with torsion? Is there an inspection method? jacking up or something? or otherwise

[QUOTE = aliyasin] As you said, there is a crack sound that does not always come, usually when maneuvering. If you find out why I would like you to share. [/ QUOTE]

I couldnt find it. It went by itself. I did not take it to the repairman, they will spend money and pay for it.
