How often should control bushings need to be replaced ? I have already had them replaced twice. Last time in March 2019

What is your question?

Lower control bushings . I have about 20 k miles on car since last replacement. Dealer charged $600. That seems high. My question is how long should lower control bushings last ? How much should it cost to have them replaced

What makes this problem better or worse?

Car vibrates badly when speed approaches 60 mph

How long has your 2015 Subaru Forester had this problem?

About a month
