2000 Camaro rear end knocking

I have a 2000 camaro and im not really sure whats wrong with it.everytime i turn to the left the rear end knocks, but if i push on the gas at the same time as im turning left the knocking will stop. it doesnt do it when i turn right. the rear end lube is fine ,and the limited slip additive is also fine. i think its a bearing, but i just wanted to get some more ideas before i tear into it. thanks for your help...

is your car an LS1 stick car? If it is your rear end is just another 10 bolt casulity. GM for some reason thinks that the 7.5" 10 bolt is the best rear end ever made :rolleyes: . Anything to cut costs I guess...
