I have replace all of them about 2-3 years ago,all were bought from Honda dealer.I put winter tires on my car and went for alignement and to my surprise i back upper bushing(small one that goes to the body part,about 5" long) is totally worn out,all other are fine. I'm thinking to replace them all with eurethane ones.Is it worth it? What are the life expectancy of the OEM ones? Thanks!
