I have replaced bushings 3 times, struts front and back, shocks and sway bar pins 2 times. I drive city roads to work only 5 miles from my house. I only have 77,586 miles on my car and a lot of problems for that type of use. We have a 1998 chevy tahoe that we love. You should stand behind your bad products that you put out.
