Never in my life have I gone through so many of the same part...You'd think a company that offers a lifetime warranty on a product would build it well so they don't have to dish out replacements all the time. I've gone through 5 of them this year. I don't even drive very hard. My most recent one which I put in last week is already clicking. The others slung grease within days but lasted a few months. Of all the bad reviews they get online, am I crazy to think they would make more money by making a better product than giving out a bunch of free replacements? I've had enough, going to try and see if Advance will give me my money back instead of a replacement and get a WBS one.
