Review on KYB SM5437 Insulator by Cory Mosley

Replacing an old, worn out strut means replacing this isolator and shock absorber (strut mount). strut spring from the base. AN INTERESTING FACT: There is a rubber isolator on top of the spring just below the strut kit. This rubber isolator is an essential part when replacing the strut, upper bracket and lower isolator kit BUT: This rubber isolator is NOT available except at a Buick dealer which means you will pay an arm and a leg for one and have one wait a few days for it to be delivered to you
