The LR4 got it's third set of LCA's after the cheapies (eurospare? lasted 4 years and 35k kms) puked the oil and it was clunk clunk clunk. I was a little nervous of the solid bushing design vs the oil hydro bushing but ride quality does not seem worse. Let's see if they last but the arms looked to be quality. I would recommend at this point if you need to replace your LCAs. I got them through Lucky8.
