Ack! If it truly is the same as the 123, the valve is actually pretty robust. I don't know what "valve ball" they are referring to - I didn't see any inside the valve I had apart. But that still doesn't explain your problem. Did the suspension level change when you broomsticked the valve? It should. I usually put blocks under the rear tires and operate the valve by hand. -- Philip _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
