Bringing old thread back to life ....ha....I have the same issue on my 335i Bilstein PSS10. When riding slow over small bumps makes pop pop noise. At high speeds and cornering you can't hear anything and is stable. Only when rolling about 5 - 10 mph over small bumps or inclines like you said. I have been driving like this for 1 year can't pin point the problem. Also like you said if you push down hard on the front of the car while parked makes pop pop noise. I am beginning to think that this is the guide Part# 31306775098 but uncertain as everything is tight. I do have vorshlag camber plates laying around which have a bigger bearing than stock. I might replace and see. Let me know if you actually found the culprit of this problem. Thanks! Oh ha I only have one washer and I did the install my self 3 years ago with no issues in the 1st 2 years.
