I bought my LC at 207K last year. In the past 8 months or so I have replaced all shocks, end links and their bushings, sway bar bushings and steering rack bushings. All of these bushings on mine were in pretty bad shape.
The LC now feels great, a bit soft for my taste, but my wife loves it. It is much more stable at high speed, and soaks up bumps nicely.
I replaced things one item at a time because I wanted to be able to feel how it change the ride, and I just do not have time to do all of them at the same time. Two things that make the most significant improvement imo are new OEM shocks and steering rack bushings. Next on my list is the rear springs, probably going to get aftermarket springs since they are cheaper than OEM.
