I have the same experience last week, I ordered a pair of TRW ball joints(left & right), 4 upper front sway bar bushing, 2 lower sway bar bushing & 2 sway bar bushing. When I openned the box the ball joints are two diff. brand, a TRW & Moog. No big deal supposed to be but one is missing a nut, then the lower sway bar bushing are two diffent kind, and the sway bar bushings diameter are too small when i fitted in my car. I said to my self are this people drunk on the job or what. So, I called them that I'm upset with this and I'm returning the whole package back. Where's the quality control?
