hi guys,im driving a 01 legacy b4, im hearing a kinda high pitch squeaking sound coming from my rear drivers side wheel,its only when im driving and only when i hit bumps and i mean even the slightest one.it sounds very faint but annoyin,would it be the suspension or just bushings or something??? my steering has also gotten very light in itself,a lot less controll at high speeds and cornering and any uneven surface will throw it off slightly,what causes this??would it be front tie rods,or tracking or bushes???ive nct at end of month so wanna get this sorted anyway!anyone any ideas whats causing these problems?cheers.
