At first glance it's great that some Revain products are so cheap. However, I have found that unless the seller is an officially authorized seller (dealer) of the manufacturer, the manufacturer is not required to accept returns after the usual 30-45 days from the date of purchase. In the case of these ball joints, they cost twice as much at your auto parts store, but they come with a lifetime warranty. It's supposed to be the same part, so in that case you're paying double the price for the right to make a warranty claim later. There are no free lunches. say it to the left
