i work at autozone most of the suspension parts that are "duralast" are made by perfect circle and moog. they just put the duralast name on it so autozone can offer a lifetime warranty. all duralast parts execpt batteries have a lifetime warranty. as far as wheel bearings go id get timken (which Autozone stocks" or oe which i beleve are koyo or something that sounds japaneese like that

what ever you do do not get the valucraft brand...aka valu-crap. they have TRW and some other cheesy stuff. but valucrap offers a 1 yr warranty on all suspension parts and wheel bearings
