Does fluid in boot on rack & pinion require r&p replacement?

Hello, Yes it requires replacement, and no, the control arm replacement would not necessarily allude to steering rack failure because the rack is sealed from the factory. The boots on the end act like accordions/bellows when you turn, stretching so they do not tear from extension and retraction. In order to know there is an internal fluid leak into the rack and pinion, the boot must either be leaking externally, or suspected of leaking, and subsequently inspected. I would like to think a 2009 model would not need a steering rack replacement, but if the boot was ever slightly damaged, or if dirt/debris has entered the system at all, it will happen.
