common for the axles to click. If you loosen and re-tighten the axle nuts it takes care of the problem. Not sure if its similar issue to you but does it happen from take off or while driving down the road already? But it could be a number of things if its mechanical I am just telling you of a common issue.

its mostly when i take off, only on hard acceleration, this sound is not a clicking sound its more like a ping/chain sound. it does not do it while i'am driving down the road, however when the car is in parking and i hit the gas all the way i can hear it. i think this sound seems to be coming from either the motor or trans, can it be one of the valves, or is my engine in trouble???

it could be but it may be the type of gas you put in your car. What grade do you use? Lower octane usually can cause a pinging sound from the engine so if you have been using 87 or 89 the way to cure this is use higher octane.

well i have been using 93 supreme gas since i bought the car, even tried three different gas stations nuttin.....

well the last thing to do is get a buddy, a stethoscope, and get under the hood and listen at different areas to see if you can't pinpoint the noise. As for now without hearing and or seeing the car it hard for me to tell you.
