Yes, that is it purpose,but it not help much.....coz still must change engine oil.
opt-ion, what i mean is bushing that attach my lower arm with my body its absorb vibration and protect moving part like engine mouting. What you mean from my understanding is call CV joint its conected to your steering. That why it sound 'klak, klak' when turn your steering. this CV joint easly damage if its cover tear off and sand get in.
its time for you to change it bro...
