I was sore longer than that...

People should check their manuals while their MB dealers are open before they tear into this repair because some use a crush washer instead of allowing for play..
You still need an indicator... but it is something like measureing it and then compressing it a tiny amount and measureing it again.. if you tighten it too much you are supposed to take it apart and start over....the compression washer can only be used once... so if you take the thing apart you need to have that in order to put it back together.. hince the suggestion you read the manual while your dealer is open...
My wagon was a real bear.... that special socket is available for about $27 somewhere , I found out after paying $45 for it...
