Hello dear forum, my W220, year 1999 is currently in the workshop… originally to replace the crossbar (because of the adjusted track). The workshop has just informed my wife that unfortunately the vehicle cannot be repaired, because special tool is needed: ball heads (front) are knocked out, have game. Are pressed on the axles to be able to exchange these special tool is needed. Unfortunately can not do much with this information and do not have the the possibility to call the workshop… Is the armrest the same as the crossbar? If the ball heads cannot be changed, can not the whole part (which?) be exchanged without special tools? Thanks for a short info… Best greeting, Schutzschi P. S.: Or is the support joint the “Corpus delikti”?
