Well the O.E. leaf bushings are about gone they are squeaking and feels like something is loose... wonder why. and its time to replace them. I did some searching here and just on the internet and found Polyurethane from Energy Suspension. I would Much rather have those over the OE rubber, but has anyone installed them and had good over bad or vise versa? I had No idea that they were out there till I did some searching and now I want some. What is it going to take for me to install these. A day, couple of hours, with no lift or air tools.. yeah that part sucks. also would it be a good idea to do the sway bars and anything else while im at it?
