Many other b5's have these replaced? I noticed some grease on my new wheel this week, but did not think that it could happen to me. Anyway, I am attempting to raise my adjustable bilstiens one notch because the car is rubbing the fender liner( would have been rubbing metal had I not rolled the fenders), and thru the pain of trying to get the bolt out of the lower control arm, which is so tight I dont know if I can do it, I noticed this. It does not look bad, just a small tear, but obviously its losing grease. I am not going to fix this one, I have only watched this done once and I know I will mess it up. How many hours of labor and parts will this cost me, there are no clicking noises, it seems to be operating fine.
