I got mine from
http://www.1aauto.com/1A/wheel-beari...Alero/-/-/2002
bought the pair for 189 over 4 years ago think i only paid 160 though
after a year i had to replace the passenger side after 2 years the driver.
knock on wood!! so far the replacements have lasted longer then the OEM ones which i had replaced every year with GM warranty.
