The rubber associated with the strut itself, definitely replace. The other suspension components that have rubber is a judgement call. I’d replace dry cracked rubber parts. Sway bar bushings will begin to waller out and be less effective. Cracked rubber boots (ball joints, sway bar links ,CV axles) can eventually rupture loosing the grease.Would you recommend changing all the rubber parts with the struts or can I get away with just doing the struts?
