Whatever happened to customer service????

I worked in a front end specialty shop for about 5 years when I was a kid in the 70's all you really need is a socket and a big hammer, if one bushing has a sleeve around it you will need a air chisel to remove it but if not just find a big socket that is bigger than the bushing on the outside put the socket on the floor put the bushing in the socket so the arm is on the socket and hit the inside of the bushing with a 4 lb hammer and it will pop right out.
