Pick-N-Pull is a butt rape.

Well yeah it is different. First off,all a scrap yard does with true rebuildable cores is scrap them. Secondly, like he said in his original post, you caint rebuild a sway bar anyway, so putting a core charge on something like that is just theft.

Parts stores need the core part to keep the chain of rebuilt parts going. Big difference.
The core charge is so they get their scrap back. You buy a rear end and return the old broken one back they get their scrap back. You just paid for the part. Core has nothing to do with rebuilding like a parts store does unless they sell those parts to rebuilders. No waste at scrap/salvage yards.
