hey guys!!--need to get new wheel bearings/hubs for my trailblazer. at advance auto parts they are about 260.00 bucks each found some on e-bay for 109.00 each, new with a lifetime warranty,whatever thats worth. i found them at autopartsdirect2you. i guess my question is, am i cutting out the"middle-man" or am i buying junk? anyone have experience in this area they would like to share? thanks alot!!!
