I installed some rebuilt tubular shock links on the front of my sedan, original shock arms and link tubes. These do not stand plumb, used new rubber and grease covers. Rotating rubber and steel grease covers did not help. Wondering if anyone else has noticed this. Wondering as well if perhaps the rubber grease covers may not be manufactured correctly as compared to my other set purchased a few years ago. On my other A installed two years ago they are plumb.
