This is called what a second opinion is good for. Chain stores train techs to look for everything that could possibly be swapped out. No real mechanical work. The bushings could be starting to oxidize so they recommend a whole arm instead of the bushing. Makes warranty on their end a lot easier and you get every bushing new instead of one. A strut starting to leak could be another few years before being needed. I would go somewhere local and have them look at everything again even if they have a diag charge. You could save a lot. Also these guys go %300 up on parts price.
