Thanks for the good info guys. I've always heard heim joints need to be replaced every couple years and were bad for nvh but I never knew the jj had better longevity and less nvh. Can any one explain the differences between them or point me to a good website?
Edit: Never mind, I found them on Currie's website lol. I never knew there was urethane in a johnny joint, pretty cool design. There's a video on Currie's site
