I replaced my front sway bar bushings just because it’s been 100k miles on the originals. The old ones actually looked pretty decent. Probably didn’t need to do it, but I had the parts. I also replaced my Mountune RMM with a new Vibratechnics unit I got from Whoosh. I was hoping for reduced NVH on fresh rubber vs 90k mile urethane, bit early impressions are not really any different. I plan to sell the Mountune RMM and the set of replacement bushings I bought last year but never used.
