today when i jack up the rear of my car, i notice that there are oil/grease splashed all over the bump stopper and the top portion of the rear shock. Is my rear shock leaking from the top? I am running on bilstein sport with H&R race spring. anyone has the same kind of problem before? what should i do if it is leaking? various people told me that the bump stopper is leaking (but i don't think so). I can see that the oil leaks starts from the middle of the bump stopper all the way down to the shock. any suggestion? thanks in advance.
